La miopia es un caracter bastante comun en la especie humana. Un matrimonio en el que ambos conyugues poseen vision normal, tienen dos hijos, uni con una vision normal y el otro con miopia. Teniendi en cuenta el fenotipo de todos los miembros de la familia ¿quenpodrias deducir del gen que controla la miopia? ¿ que genotipo podrias asignsr a cada individuo?

Answers

Answer 1

Answer:

El gen que controla la miopia es dialelico, autosómicoEl alelo dominante M expresa visión normal, El alelo recesivo m expresa  miopia, Los padres con visión normal serían heterocigotas, Mm.Tendrían un hijo con visión normal homocigota dominante MM o Heterocigota Mm   Tendrían otro hijo homocigota recesivo con miopia, mm.

Explanation:

Datos disponibles:

Ambos padres poseen visión normalUno de los hijos tiene visión normalEl otro hijo tiene miopia

Podríamos establecer que M es el alelo dominante, mientras que m es el alelo recesivo.

A partir de la información brindada, podríamos suponer que:

Opción 1:

La miopia es un caracter expresado por un gen dominante. Si este fuera el caso, entonces al menos uno de los padres debería tener miopia para poder heredarle al hijo el alelo dominante para expresar el caracter. Si este fuera el caso, los posibles genotipos de los padres serían:

Parental)  Mm   x   mm (al menos uno de los padres con miopia)

F1) 1/2 Mm (Hijo miope)

    1/2 mm (Hijo con visión normal)

Pero en este caso, los dos padres tienen visión normal, entonces si el gen dominante expresa la miopia, los genotipos de los padres serian homocigotas recesivos, mm. Si ambos padres son homocigotas recesivos, no podrían heredarle a ningun hijo el alelo de la miopia. En este caso, la cruza sería:

Parental) mm    x    mm

F1) 100% mm (todos los hijos con visión normal)

Sin embargo, para el ejemplo planteado, los dos padres tienen visión normal, uno de los hijos tiene visión normal y el otro tiene miopia, lo que nos conduce a la segunda opción.

Opción 2:

La miopia es un caracter heredado por un gen recesivo, m. Mientras que la visión normal es heredada por un gen dominante, M. Entonces, si este fuera el caso, para que ambos padres con visión normal, tengan un hijo homocigota recesivo para el caracter, entonces ambos padres deberian ser heterocigotos. Su hijo miope heredaría un alelo recesivo de cada padre y expresaría el defecto. El genotipo de las personas con miopía sería entonces homocigota recesivo. Esta cruza sería de la siguiente manera:

Parental) Mm    x    Mm  (Ambos padres heterocigotas)

Gametos) M   m     M     m

Cuadro de Punnet)

                M             m

     M       MM         Mm

     m       Mm         mm

F1) 3/4 o 75% de probabilidad de tener un hijo con visión normal

    1/4 o 25% de probabilidades de tener un hijo miope.

Entonces, podemos concluir que:

El gen que controla la miopia es dialelico, autosómicoEl alelo dominante M expresa visión normal, El alelo recesivo m expresa  miopia, Los padres con visión normal serían heterocigotas, Mm.Tendrían un hijo con visión normal homocigota dominante MM o Heterocigota Mm   Tendrían otro hijo homocigota recesivo con miopia, mm.

explain why soil micro-organisms should break down plant and animal residues​

Answers

Hello there wish you a GREAT Thanksgiving :)

Microbial Soil Orga​nic Matter Decomposition

Organic matter decomposition serves two functions for the microorganisms, providing energy for growth and suppling carbon for the formation of new cells. ... Dead plant residues and plant nutrients become food for the microbes in the soil.

Microbes thrive underneath no-till conditions and winter cover crops. cowl plants and manure may be used to feed soil microbes and recycle soil vitamins. As soil microbes decompose organic residues, they slowly release vitamins lower back into the soil for the winter cowl vegetation or for the preceding crop.

Why soil microorganisms should break down plant and animal residues?

By-products from growing roots and plant residues feed soil organisms. In turn, soil organisms support plant health as they decompose organic matter, cycle nutrients, enhance soil structure and control the populations of soil organisms, both beneficial and harmful (pests and pathogens) in terms of crop productivity.

What's the significance of microorganisms within the soil what's their role?

Useful soil microbes carry out fundamental capabilities which include nutrient cycling, breaking down crop residues, and stimulating plant boom. at the same time as the position of microbes to preserve soil fitness and make contributions to crop performance is clear, the soil organic factor is extremely difficult to take a look at and control.

If 100 mice are bred, how many red eyed white mice would you expect?

Answers

Answer:

6

Explanation:

In this scenario, black fur (F) is dominant to white fur (f) and black eyes (E) are dominant to red eyes (e). So in this case you would be looking for all lowercase letters in the punnet square, which would only be 1 mouse with white fur and red eyes (ff ee), and since there are 16 potential genotypes for offspring and only 1 that would be white with red eyes, you would divide 1 by 16 and get 0.0625, then you would multiply 0.0625 by 100 (total number of mice) and you would get 6.25. since you can't really have .25 of a mouse (that would be kind of gross) you round down and get 6, the closest answer.

Which two structures produce energy that cells can
use?
O A and B
OB and C
O Cand D
O D and A

Answers

Answer:

According to the plant cell scheme, the two structures that produce energy that cells can use are D, which corresponds to mitochondria, and A, which is a chloroplast, so the answer is D and A (fourth option).

Explanation:

In the plant cell —unlike the animal cell— there are organelles called chloroplasts, responsible for converting light energy from the sun into chemical energy. In addition, there are mitochondria, which also provide useful energy to the cell.

In the chloroplast, photosynthesis takes place, a process that during the light phase produces ATP and NADPH⁺ from solar energy. In the mitochondria, energy in the form of ATP is obtained from glucose, due to oxidative phosphorylation and the electron transport chain.

The organelles indicated in the diagram are mitochondria (A) and chloroplast (D), both responsible for producing energy for the plant cell.

what is the biodiversity score of farmland (maize)?

Answers

Answer:

Required Answer:-

The intensification of agriculture has caused dramatic declines in farmland biodiversity (Carvalheiro et al., 2013; Senapathi et al., 2015). Since the 1990s, agricultural policies have been developed in Europe to mitigate this loss through agri-environmental schemes (AES). One AES is “sown wildflower strips”, the aim of which is to create new ecological infrastructures by sowing attractive wild flowers on arable land (a few % of the cultivated area). These ecological infrastructures fall within our definition of MIMS since they represent a massive introduction of managed species in the landscape.

In 1851, Gregor Mendel, a young monk in Europe, formed the foundation of genetics by using pea plants. In one of his experiments, Mendel crossed yellow pea seeds with green pea seeds. Much to Mendel’s surprise, all of the offspring were yellow peas.

Which of the following statements explains Mendel’s results?

A.When the two peas were crossed, the offspring received genes from both parent plants, but the genotype for yellow seed color was dominant over green seed color.

B.When the two peas were crossed, the offspring received genes from both parent plants; the phenotype for yellow peas was dominant over green pea color, which caused all the offspring to have yellow seed color.

C.When the two peas were crossed, the offspring only received the genes from the parent plant which had the genotype for yellow seed color.

B.When the two peas were crossed, the offspring only received genes from the parent plant with the phenotype for yellow seed color, which caused all the offspring to be yellow.

Answers

Answer:

It's A

Explanation: They both have gene for both of the color but the yellow pea seed gene or whatever is dominant.

The statement that best explains Mendel’s results is when the two peas were crossed, the offspring received genes from both parent plants, but the genotype for yellow seed color was dominant over green seed color. The correct option is A.

What is Mendel's law?

Gregor Mendel was a scientist and botanist, and he experiments on pea plants and discovered three laws that are very helpful in genetics.

Mendel's law of segregation, "during gamete formation, every gene segregates from each other so that each gamete conveys only one allele for each gene." The second law of inheritance is the law of segregation.

Mendel's 2nd law of inheritance is also known as the law of independent assortment of genes.

It states that each character behaves as a separate unit and is inherited independently of any other character.

Therefore, the correct option is A.

Answer:

Explanation: This process is called mitosis. However, parental gametes – the sperm and egg cells – are unique from all other cells in that they reproduce through a process called meiosis.  The purpose of meiosis is to shuffle genetic information and cut the cellular chromosome number in half, from 46 chromosomes to 23 chromosomes.  In this way, when an egg and sperm cell combine during fertilization, the resulting embryo will inherit the appropriate amount of unique genetic information from each parent.tion:
