Question

Determine predicted phenotype ratio in children of a woman who is dihybrid for right handed and free earlobes and a man who is left handed with attached ear lobes. What is parent phenotypes,genotypes and gametes. What js the ratio of phenotypes

Answer 1

All the offspring will have genotype RrEe and will be right handed and have attached earlobes

Step-by-step explanation:

Let the dominant allele for right hand trait be "R" and the recessive left hand trait allele is "r"

Allele for attached earlobes trait is "E" and free earlobes trait is "e"

Genotype of woman who is right handed and has free earlobes - RRee

Genotype of man who is left handed with attached ear lobe - rrEE

The genotype of offspring would be RrEe

All the offspring will have genotype RrEe and will be right handed and have attached earlobes
