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?\no 100 percent ee\no 100 percent unattached earlobes\no 100 percent ee\no 100 percent attached earlobes

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?\no 100 percent ee\no 100 percent unattached earlobes\no 100 percent ee\no 100 percent attached earlobes

Answer

Explanation:

Step1: Determine parental genotypes

The parent with homozygous unattached ear - lobes has genotype EE. The parent with homozygous attached ear - lobes has genotype ee.

Step2: Set up Punnett - square cross

When EE is crossed with ee, all of the gametes from the EE parent are E, and all of the gametes from the ee parent are e.

Step3: Determine offspring genotypes

When we combine the gametes, all of the offspring will have the genotype Ee.

Answer:

100 percent Ee
