Question

rabbit.
Parent genotypes: ____________ X ____________
● What is the phenotypic ratio? ______________________
● What is the percent probability that the offspring will have short, black hair? ______________
● What is the percent probability that the offspring will have long, white hair? ______________

Answer 1

[AI-generated answer — Bot GPT 3.5]

Parent genotypes: rrbb X RrBb

Phenotypic ratio:
In this case, we can use the Punnett square to determine the genotype and phenotype of the offspring.

The Punnett square for this cross would look like this:

r r
R Rr Rr
r rr rr
B
b Bb Bb

From the Punnett square, we can see that:
- 25% of the offspring will have short, black hair (rrbb).
- 25% of the offspring will have short, white hair (rrBb).
- 25% of the offspring will have long, black hair (Rrbb).
- 25% of the offspring will have long, white hair (RrBb).

Phenotypic ratio: 1:1:1:1 (short, black hair: short, white hair: long, black hair: long, white hair)

Percent probability that the offspring will have short, black hair:
25% chance of rrbb genotype, which means 25% chance of having short, black hair.
Percent probability: 25%

Percent probability that the offspring will have long, white hair:
25% chance of RrBb genotype, which means 25% chance of having long, white hair.
Percent probability: 25%
