Directions: Solve each problem showing your work in the Punnett square. For each cross, give the genotypes and phenotypes of the offspring and the probability of getting each. List the genotypes and phenotypes in the table seen by each problem.
Answer the questions that accompany each problem.
What vou need to know about
the mice: In laboratory mice, gray coat color (G) is dominant over albino coat color (g).
I. Cross a female Gg with a male gg.
(Example is the picture)
NEED HELP WITH TWO:
1. Cross a gray female, whose father was albino, with a heterozygous male.
(The same box in the example picture / needs to be solved)
(the same genotypes and phenotypes list / that needs to be solved)
1. What is the probability of getting gray offspring?
2. What is the probability of getting albino offspring?
3. How many possible genotypes are there among the offspring?
4. How many possible phenotypes are there among the offspring?
5. What is the probability of getting heterozygous offspring?
6. What is the probability of getting homozygous offspring?
7. What is the genotype of the female? How do you know?
8. What is the genotype of the male? How do you know?
2. Cross an albino female, whose father was gray, with a gray male, whose mother was albino
