A farmer is trying to increase the diversity of corn kernel color in his crops. The trait for corn color is controlled by two alleles. Yellow corn (B) is dominant over white corn (b). Which combination of corn should he cross to get the most variety of genotypes for corn color in the next generation?
A. BB x BB
B. Bb x bb
C. Bb x Bb
D. BB x bb
Answer:
C
Explanation:
If the farmer crosses Bb x Bb, then the progeny will have BB, Bb and bb genotypes attributing to increased diersity of corn kernel color in his crops.
What is a genotype?The total complement of an organism's hereditary material is referred to as its genotype. The alleles or variants that an individual carries in a specific gene or genetic region are also referred to as their genotype. Genotype is another term for them.
There are three distinct categories of genotypes: heterozygous recessive (pp), heterozygous dominant (PP), and homozygous recessive (pp). Both the dominant homozygous genotype and the dominant heterozygous genotype exhibit the same characteristics.
Therefore, if the farmer crosses Bb with Bb, the offspring will have BB, Bb, and bb genotypes, which will contribute to an enhanced diversity of corn kernel color in the farmer's harvests.

If the anticodon of a molecule of tRNA has the sequence GAU, what was the original DNA sequence?
Answer:
CTA
Explanation:
DNA to RNa
A---> T
C--> G
RNa to dna
A--> U
C---> G
If the anticodon of one molecule of tRNA contains the sequence GAU, then CTA was the original DNA sequence.
What is DNA sequencing?
DNA sequencing is defined as the laboratory procedure used to determine the exact sequence or order of the four building blocks or bases that make up DNA. Information that is stored in DNA in a code which is formed by arranging the four bases which are adenine, cytosine, guanine and thymine which are identified by letters A, C, G and T in different order.
Within double-stranded DNA, nitrogenous bases on one strand pair with complementary bases on the other strand. A always pairs with T, and C always pairs with G, during DNA replication, the two strands separate into a double helix.
Sequence of tRNA is GAU, so the DNA sequence is CTA as C complements to G, A to T and U to A as in RNA Uracil is present in the place of thymine.
Thus, if the anticodon of one molecule of tRNA contains the sequence GAU, then CTA was the original DNA sequence.

On the first day after arriving in Miami for spring break vacation, Matt plays out in the sun for six hours. Later that night he notices that the skin on his legs and arms becomes red, swollen and extremely painful. By morning all of the afflicted areas have developed numerous blisters. These areas cover about 30% of his trunk (front and back) and 40% of the arms and legs.What organ has been damaged? What general types of tissue have been afflicted?What type of burn has Matt received? Explain.List ALL layers of the skin that have been damaged.What tissue repair process causes the blistering?List all of the body functions that may be disrupted by such a burn.After a few days his skin peels and the burned areas begin to heal. Matt notices that the healing areas are more susceptible to injuries due to chafing or trauma. During the next week after Matt returns to Tampa, Maria tells him that a sunburn prepares his skin for a deep tan. Maria encourages him to quickly begin tanning sessions at a local tanning salon before the effects of the burn wear off.What has happened to the skin that would cause this increased susceptibility?What would you advise him to do? Why?Is a deep tan a sign of skin that is healthy or severely stressed? Explain.
Answer:
Miami is is kanada

The question the scenario shows suggests, the integumentary system of Matt is affected, this system is part of the skin.
What is sunburn?A person having lesser melanin content in their skin has the risk of developing redness, swelling, and pain in the skin indicative of cellular damage caused by excessive sun UV radiation, this is known as sunburn.
Matt received a second-degree sunburn, which affects the dermal and epidermal layers of the skin. The inflammatory stage, proliferation stage, and matrix remodeling are the tissue repair process.
The skin is the first line of defence and acts as a barrier, after this injury affect this line of defence is affected causing entry of pathogens inside the body.
In absence of the epidermis, when the dermis is exposed, easily bruises and injury occur since blood vessels are exposed to the skin's surface.
Therefore, excessive exposure to the UV light creates deep tan signs.

The gene for nose shape is found on the X chromosome. Round nose is dominant to pointed nose. Human individuals with XXY (an additional X chromosome) are designated male. Individuals with XO (only one X chromosome) are designated female. Identify the possible nondisjunction events (rare mistakes during meiosis) that could explain the phenotype of the offspring. An XY parent with a round nose and a XX parent with a round nose have an offspring with Klinefelter Syndrome (genotype XXY) with a pointed nose.
Answer:
Explanation:
in this case female parent XX is hetrozygous for round nose. when a cross between round nose father XY and hetrozygous round nose mother takes place and suddenly a chromosomal nondisjuction occurs, the chromosomes carrying genes for pointed tip nose come togather in a gamete and a gamete (egg) with XX chromosomes is appeared having 24 chromosomes instead of 23. when this gamete fertilizes with a sperm having normal 23 chromosomes and only carry Y chromosomes, a pointed nose klienfelter syndrome case will appear.

Answer:
c)both DNA and RNA
explanation
When it is attached to a molecule containing carbon, it is called a phosphate group. It is found in the genetic material DNA and RNA, and is also in molecules such as adenosine triphosphate (ATP) that provide energy to cells. Phosphates can form phospholipids, which make up the cell membrane.
Identify the correct sequence of molecules, as a gene goes from coded information in the nucleus, to the product the cell wants to make.

Mutations and variation occur randomly. True\ False
Answer:
true
Explanation:
What animal is this
A strain of Drosophila known as dunce produces one-half the amount of cAMP phosphodiesterase found in wild-type flies, which causes a learning defect. Another strain of Drosophila known as rutabaga produces a defective adenylyl cyclase protein (one of the AC types expressed in most cells) and also causes a learning defect. A dunce - rutabaga double mutant fly has relatively normal learning. Explain these curious observations.
Answer:
From the given observations we can say that there are 2 genes that are responsible for normal learning. It is also given that the dunce and rutabaga mutations are the mutations of 2 different genes.
Due to complementation which is a phenomenon of restoration of normal phenotype if mutants are crossed, it is found that the flies have normal learning behavior if both mutants are crossed.
Let's assume that the Drosophila having this learning effect and it is due to genes D and R where D is the normal gene and dd is the case of mutation that results in duncy phenotype. Similarly, Gene R is responsible for normal learning, and rr results in rutabaga phenotype.
Cross between ddRR (duncy) x DDrr (rutabaga)
Gametes - dR x Dr
F1 progeny - DdRr
Thus, in heterozygous cases, a single copy of both wild-type alleles D and R complement each other.
