Earlobes are an inherited trait. Attached earlobes are recessive (e) and free earlobes (E) are dominant. If a heterozygous man with free earlobes reproduces with a woman with attached earlobes, what possible earlobes will the children have? Create punnet square

1/2 free earlobes (Ee) and 1/2 attached earlobes (ee)

Explanation:

This question involves a single gene coding for earlobe attachment or not. The allele for free earlobes (E) are dominant over the allele for attached earlobes (e). This means that a heterozygous individual (Ee) will possess a free earlobe.

According to this question, If a heterozygous man (Ee) with free earlobes reproduces with a woman with attached earlobes (ee), the following gametes will be produced by each parent:

Ee - E and e

ee - e and e

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Ee, Ee, ee and ee

- Children with genotype Ee (1/2) will have free earlobes

- Children with genotype ee (1/2) will have attached earlobes

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
