Detailed explanation-1: -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.
Detailed explanation-2: -In Mendelian genetics, this means that an organism must be homozygous for every trait for which it is considered true breeding; that is, the pairs of alleles that express a given trait are the same. In a purebred strain or breed, the goal is that the organism will “breed true” for the breed-relevant traits.
Detailed explanation-3: -purebred. adjective. pure·bred-ˈbred. : bred from members of a recognized breed, strain, or kind without cross-breeding over many generations.
Detailed explanation-4: -An organism that has two identical (same) alleles for a trait is called a purebred.
Detailed explanation-5: -Homozygous, or homozygosity, refers to the inheritance of genes from each biological parent. The variant results from a mutation that changes the DNA sequence making up a gene. Experts refer to variations in genes as alleles. If the alleles are identical, a person is homozygous for that gene.
