Hummingbirds have brightly colored feathers on their throats that are Let's say these feathers come in three different colors red (R), yellow () and yellow alleles are codominant when present together, and both re dominant when paired with the recessive grey allele. (Hint - this is the s groups in humans and, is not sex-linked). please show your work. a. A grey female mates with a yellow throated male and she lays 4 eg chicks have yellow-colored throats. What is the genotype of the m chicks? b. The next year one of the female chicks from the nest above grows male that has both red and yellow feathers. What will be the genot their offspring, and in what proportion? Assume 4 young.

Question
Hummingbirds have brightly colored feathers on their throats that are used to attract mates. Let's say these feathers come in three different colors red (R), yellow (Y) and grey (g). The red and yellow alleles are codominant when present together, and both red and yellow are dominant when paired with the recessive grey allele. (Hint - this is the same as the ABO blood groups in humans and, is not sex-linked). please show your work. a. A grey female mates with a yellow throated male and she lays 4 eggs. All of the resulting chicks have yellow-colored throats. What is the genotype of the male that fathered the chicks? b. The next year one of the female chicks from the nest above grows up and mates with a male that has both red and yellow feathers. What will be the genotypes and phenotypes of their offspring, and in what proportion? Assume 4 young.
