An individual with a dominant phenotype is crossed with an individual with a recessive phenotype. Five out of nine offspring show the dominant phenotype. What is the genotype of the dominant parent?

A) homozygous dominant
B) heterozygous
C) homozygous recessive
D) either homozyous dominant or heterozygous
E) There is not enough information to determine the genotype of the dominant parent.

Dominant Phenotype

Refers to the trait that appears in an individual's phenotype when at least one dominant allele for a particular gene is present.

Recessive Phenotype

An observed trait or characteristic of an organism that results from having two recessive alleles for a particular gene.

Heterozygous

Genetically describes an organism that has two different alleles of a gene, one inherited from each parent.
