Question

unattached earlobes is a dominant trait, e. a parent who is homozygous for unattached earlobes is crossed with a parent who is homozygous for attached earlobes. which describes the genotypes of their offspring? 100 percent ee 100 percent unattached earlobes 100 percent ee 100 percent attached earlobes

Explanation:

Step1: Determine the parents' genotypes

A parent homozygous for unattached earlobes (dominant trait) has genotype \( EE \). A parent homozygous for attached earlobes (recessive trait) has genotype \( ee \).

Step2: Perform the cross

Using a Punnett square:

	\( E \)	\( E \)
\( e \)	\( Ee \)	\( Ee \)

Answer:

100 percent \( Ee \)
