Question

1.The trait for green eyes is dominant (Y) to brown eyes which are recessive (y). Determine the eye color a child will have with a Yy genotype:
☐Blue Eyes
☐ Green Eyes
☐ Hazel Eyes
☐ Brown Eyes
2. A bird that is heterozygous for the yellow feather trait is crossed with a bird that is homozygous for the white feather trait. The yellow trait is dominant to the white trait. What are the genotypes for feather color of both birds?
☐Yy, YY
☐YY, YY
☐Yy, Yy
☐Yy, yy

Answer 1

1) Green Eyes

The child will have green eyes with a genotype of Yy because green is dominant and the green trait (Y) is present.

2) Yy, yy

You can find this answer by making a punnett square and crossing the Yy and yy genotypes.
