Sex-linked Inheritance Answers

Genes are segments of DNA that are the basic unit of heredity. They are passed on from parent to offspring. The gene form of a trait is called a(n) homozygousphenotypeX allelerecessiveheterozygousdominantgenotype.An organism’s allele combination is called the homozygousphenotypealleleX recessiveheterozygousdominantgenotype.The physical appearance of an organism is called the homozygousphenotypeallelerecessiveheterozygousdominantX genotype.

There are two types of alleles. An allele that masks another is the homozygousphenotypeallelerecessiveheterozygousdominantX genotype allele. The one that is masked is called the homozygousphenotypeallelerecessiveheterozygousX dominantgenotype allele.An organism that has the same alleles for a particular trait is homozygousphenotypeallelerecessiveheterozygousdominantX genotype. An organism that has different alleles for a particular trait is X homozygousphenotypeallelerecessiveheterozygousdominantgenotype.
