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

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.

1. To determine the eye color a child will have with a Yy genotype, we need to understand the principles of Mendelian genetics. In this case, the trait for green eyes (Y) is dominant over the trait for brown eyes (y), which is recessive.

- The capital letter 'Y' represents the dominant allele for green eyes.
- The lowercase letter 'y' represents the recessive allele for brown eyes.

A child with a Yy genotype will have one copy of the dominant allele (Y) and one copy of the recessive allele (y). Since the dominant allele is present, the child will have green eyes.
Therefore, the correct answer is: ☐ Green Eyes

2. To determine the genotypes for feather color of both birds, we need to know that the yellow trait is dominant (Y) while the white trait is recessive (y).

- The capital letter 'Y' represents the dominant allele for yellow feathers.
- The lowercase letter 'y' represents the recessive allele for white feathers.

The bird that is heterozygous for the yellow feather trait has one copy of the dominant allele (Y) and one copy of the recessive allele (y) - its genotype is Yy.

The bird that is homozygous for the white feather trait has two copies of the recessive allele (yy) - its genotype is yy.

Therefore, the correct answer is: ☐ Yy, yy
