d. Using a branch diagram, determine the proportion of each type of offspring expected from this cross of the two turtles with black shells and yellow specks (from above). If the turtle pair had 128 offspring, how many offspring would you expect of each type? e. Mate the female turtle described above in a test cross. Use a branch diagram to determine the expected proportion of each phenotype of turtle, and the expected numbers if they had 128 offspring.

Hi can you help with d & e?

Two turtles were mated and produced a large clutch of baby turtles. Both parent turtles had black shells with yellow speckles. Their offspring were a mix of turtles with
black shells and yellow speckles, gray shells and yellow speckles, plain black shells with no speckles and plain gray shells with no speckles.
a. Which shell color is dominant?
b. Which speckle pattern is dominant?
c. What are the genotypes of the parents? Specify your alleles.
d. Using a branch diagram, determine the proportion of each type of offspring expected from this cross of the two turtles with black shells and yellow specks (from
above). If the turtle pair had 128 offspring, how many offspring would you expect of each type?
e. Mate the female turtle described above in a test cross. Use a branch diagram to determine the expected proportion of each phenotype of turtle, and the expected
numbers if they had 128 offspring.
