Hello Heliodors! (cont.) Trait A For Heliodors, having four arm-like extensions is dominant over having two. In a family of Heliodors, Hayden has four arm-like extensions like his mother Helen. His father, Harry, and sister, Holly both have two. What are the genotypes of everyone in this family of Heliodors? What is Harry's genotype? Not enough information to determine AA (homozygous dominant) aa (homozygous recessive)

Expert Solution
Step 1

The alleles are the alternative forms of agent that are located on the same locus of a homologous chromosome. In case of diploid (2n) organism usually two alleles are present (except in case of multiple allelism), that are dominant or recessive in nature.

According to Mendelian inheritance and law of dominance heterozygous individual will express only the dominant phenotype.
