Detailed explanation-2: -If the two alleles are the same, the individual is homozygous for that allele. If the alleles are different, the individual is heterozygous.
Detailed explanation-3: -Purebred-Also called HOMOZYGOUS and consists of gene pairs with genes that are the SAME. Hybrid-Also called HETEROZYGOUS and consists of gene pairs that are DIFFERENT. Genotype is the actual GENE makeup represented by LETTERS.
Detailed explanation-4: -b) If the genotype of an individual has the same (identical) alleles for a given trait, it is called a homozygous genotype. This genotype is found in purebred individuals which are bred from members of a recognized breed or strain without cross-breeding over several generations.
