2. What can be inferred about the genotype of II-5 based on that person's descendants?

The thing that can be inferred about the genotype of II-5 based on that person's descendants "his grandkids have it."

Explanation:

Genotype is the group of genetic factor accountable for the numerous inherited characters of a specified creature. Genotype denotes precisely to the genetic factor, not the characters; that is, the fresh data in an creature's DNA. An allele can be finished up of two dominant genes, a dominant and a recessive gene, or two recessive genes. There are three accessible genotypes, PP (homozygous dominant), Pp (heterozygous), and pp (homozygous recessive). All three have diverse genotypes but the first two have the same phenotype (purple) as different from the third (white).
