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

The possible earlobes that will be possessed by the children are:

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

WHAT IS HETEROZYGOUS CROSS?

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
