Question

. The Genetic Mutation has changed the new alien's skin color from yellow to purple. This new purple gene is a recessive gene and both parents have yellow skin (heterozygous). What is the probability of getting the mutated purple allele for the new aliens? in a punnett square. (Y) for dominant and (y) for recessive.

Answer 1

Thats alotta points

Step-by-step explanation:

If the new purple gene is recessive and both parents have yellow skin (heterozygous), then they would carry one copy of the purple allele (Y) and one copy of the yellow allele (y).

To determine the probability of getting the mutated purple allele (y) for the new aliens, we can use a Punnett square to visualize the possible combinations of alleles.

Let's represent the father's alleles as Yy and the mother's alleles as Yy as well. The Punnett square would look like this:

| Y | y |

-----------------------

Y | YY | Yy |

-----------------------

y | Yy | yy |

In the Punnett square, the top row represents the possible alleles from the father (Y and y), and the left column represents the possible alleles from the mother (Y and y).

The four possible combinations in the Punnett square are:

- YY (yellow skin)

- Yy (yellow skin)

- Yy (yellow skin)

- yy (purple skin)

So, out of the four possible combinations, there is one combination that results in the new purple skin allele (yy). Therefore, the probability of getting the mutated purple allele for the new aliens is 1 out of 4, which can be simplified to 1/4 or 0.25 (25%).
