The founder principle explains how rare alleles and certain combinations of alleles may be enhanced in new
AlexFokin [52]
Alleles are the alternative form of a gene that code for a given trait, the alleles may be dominant or recessive or exhibit incomplete dominance. When two alleles are similar they are referred to as homozygous while they are not similar they are referred to as heterozygous. Based on the founder effect, rare alleles and combinations may be improved in new populations because of the reduced size of the initial population.

If a homozygous blood type B father and a blood type O mother produce a child, what is the probability that the child will have
castortr0y [4]

Answer:

100%

Explanation:

Father Genotype: BB

Mother Genotype: OO

One allele will come from the father and one from the mother. Based on the parents'  genotypes, any child will take the B allele from the father and an O allele from the mother, so it will have the genotype: BO

O is a recessive allele so the child will always have blood type B.
