Our genetic code usually determines whether we have typically male or female bodies. Occasionally however, individuals are born who are genetically male, but who physically appear female

These children are ______________ male, but __________________ female.
A) heterozygous; homozygous
B) homozygous; heterozygous
C) phenotypically; genotypically
D) genotypically; phenotypically

Answer: D
Rationale: The term genotype refers to the genetic makeup of an organism. The unique set of genes that comprise every chromosome represents the genotype of the individual, while the phenotype refers to the observable characteristics, including physical structures and behaviors. In this example, a child who is genetically male but physically female has a male genotype and a female phenotype.
