Question

Mary and larry each have free earlobes and dark hair. they are both heterozygous. (e = free earlobes, e = attached earlobes, d = dark hair, d = light hair). e is dominant, e is recessive. d is dominant, d is recessive. what genotypes and phenotypes can their offspring have and what is the probability of each genotype and phenotype?

Answer 1

The genotypes and phenotypes their offsprings can have include only free lobes and attached hair.

What is Genotype?

This is defined as the genetic constituent of an organism while phenotype represents the physical characteristics.

Dd Ee when crossed will give DE, De, dE and de which means that the genotype will be homozygous dominant, heterozygous and homozygous recessive for free lobes and attached hair with the probability being 1/4 , 1/2 and 1/4 respectively.
