Answer:
Heterozygous : The state of possessing two different alleles of a gene.
Homozygous : The state of possessing two copies of the same allele.
explanation
Organisms that are homozygous are having two identical alleles for a particular trait. The alleles are represented in letters, capital or small. Example : homozygous - AA or aa
Heterozygous - Aa
Here, the dominant allele is represented by the capital letter & the recessive allele is represented by the small letter.
hope it helps.

27. Heterozygous Cp cp chickens express a condition called creeper, in which the leg and wing bones are shorter than normal (cp cp). The dominant Cp allele is lethal when homozygous. Two alleles of an independently segregating gene determine white (W_) versus yellow (ww) skin color. From a mating between chickens heterozygous for both genes, what phenotypic classes will be represented among the viable progeny, and what are their expected relative frequencies? Please show using the branch diagram method.

Which of the following statements is false? Epistasis involves interactions among different genes, to influence phenotype. When an allele is dominant, the heterozygous combination is the same phenotypically as one of the homozygotes. Dominance refers to the form of expression of a gene in relation to its allele (or alleles). Epistasis involves interactions between alleles of a single gene.
