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.

Explanation:
If false, please make it a correct statement. A rancher uses a particular chicken for breeding purposes because, on average, she observed that the chicken laid more eggs than other chickens. The rancher selecting the desirable trait would be considered an example of natural selection.
a) true
b) false
Answer:
b) false
Explanation:
The given statement is false. the selection process used by the rancher is an example of artificial selection and not natural selection.
Artificial selection is defined as the selection process done by humans on the basis of desirable characters while in natural selection the selection is based on the adaptive characteristics of animals. In the given example rancher choses a desirable character of chicken that lays more eggs.
Hence, the given statement is "false".
Short tails (T) are dominant to long tails (t). What is the probability of a long-tailed mouse in the cross Tt x tt?
25%
50%
O 75%
O 100%
Answer:
50%
Explanation:
if you do a punnett square you get two Tt and two tt. so two tt is half, which means half will be long-tailed tt, so 50%
50% of the mouse offsprings will have long tail.
According to this question, a gene coding for tail length in mouse is involved. The allele for short tails (T) are dominant to long tails (t). In a cross between Tt (short tail) × tt (long tail), the following gametes will be produced by each parent: Tt - T and ttt - t and tCrossing these gametes in a punnet square (see attached image), the following offsprings of mouse will be produced: Tt, Tt, tt and tt. Tt (2) = Short tail mice (50%)tt (2) = long tail mice (50%)Therefore, 50% of the mouse offsprings will have long tail.Learn more at: https://brainly.com/question/478887?referrer=searchResults
Summarize for prophase?
Answer:
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.
If you cross a white-eyed female (ww) to a red-eyed male (WY) Drosophila fly, you will see red-eyed females and white-eyed males in the F1 generation. If you cross an F1 red-eyed female to an F1 white-eyed male, what is the approximate percentage of total progeny in the F2 generation that are white-eyed males
Answer:
25%
Explanation:
ww gives white-eye female
WY gives red-eye male
ww x WY
F1: Ww wY Ww wY
Ww - red-eye female
wY - white-eye male
Crossing the two F1
Ww x wY
F2: Ww WY ww wY
Remember that white-eye male = wY
Percentage of wY = 1/4 or 25%
Hence, the percentage of progeny in the F2 generation that would be white-eye males = 1/4 or 25%

Acclimatization does not change ___________, so traits that arise via acclimatization cannot be passed on to offspring. On the other hand, an adaptation CAN be passed on to offspring, which means that adaptations can drive________.
If an individual coral colony can __________to the warming water, this means it might _________as the ocean continues to warm. Individuals that cannot do it will___________. It is important for these changes to__________. Natural selection ________corals that have these characteristics that enable them to tolerate warm water. So, over time, coral populations will __________to warm water.
Answer:
Acclimatization does not change Genotype so traits that arise via acclimatization cannot be passed on to offspring. On the other hand, an adaptation CAN be passed on to offspring, which means that adaptations can drive Evolution.
If an individual coral colony can Acclimatize to the warming water, this means it might Survive as the ocean continues to warm. Individuals that cannot do it will Die. It is important for these changes to Become inherited. Natural selection will favor corals that have these characteristics that enable them to tolerate warm water.

The net movement of water takes place from the ____ side to the ____ side of the membrane.
The net movement of water takes place from the Hypotonic side to the Hypertonic side of the membrane.
Where does the net movement of water take place?The net Action of water is in the order of risen solute concentrations.
An easy way to imagine this rule is just that the net water move in an area of high water concentration to an area of lower water concentration.

in a rock released?
Answer: The stress builds up in rocks. However, rocks eventually break, and the stored stress is released as energy in the form of earthquakes. ... The energy released during an earthquake migrates away from the focus of the earthquake (location of the first break of the rocks) as waves. These waves are called seismic waves.
