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
Answer
Explanation:
Step1: Determine Parent Genotypes
Homozygous dominant (unattached) is ( EE ), homozygous recessive (attached) is ( ee ).
Step2: Perform Punnett Square
Cross ( EE \times ee ). All offspring get ( E ) from one parent and ( e ) from the other, so genotype is ( Ee ) for all.
Step3: Match with Options
The option "100 percent ( Ee )" describes the genotypes. The "100 percent unattached earlobes" is phenotype, not genotype. The other two are incorrect genotypes.
