Question

wiggling your ears is a dominant trait, while not being able to is recessive. if a person is homozygous recessive for wiggling their ears... (1 point)

○ their genotype would be aa, and they would be able to wiggle their ears
○ their genotype would be aa, and they would not be able to wiggle their ears
○ their genotype would be aa, and they would not be able to wiggle their ears
○ their genotype would be aa, and they would be able to wiggle their ears

Explanation:

In genetics, for a trait where the dominant allele (let's say \(A\) represents the allele for ear - wiggling ability) and the recessive allele (\(a\) represents the allele for no ear - wiggling ability). A homozygous recessive individual has two copies of the recessive allele. So the genotype is \(aa\). Since the recessive trait is expressed when an individual is homozygous recessive, and the recessive trait is not being able to wiggle ears.

Answer:

their genotype would be aa, and they would not be able to wiggle their ears
