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. Genotype is the actual GENE makeup represented by LETTERS. Phenotype is the PHYSICAL appearance of a trait, such as a YELLOW (or BLUE) body color.
Detailed explanation-2: -Homozygous Homozygous, as related to genetics, refers to having inherited the same versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is homozygous for a genomic marker has two identical versions of that marker.
Detailed explanation-3: -Heterozygous refers to having different alleles for a particular trait. If the two versions are different, you have a heterozygous genotype for that gene.
Detailed explanation-4: -Homozygous: Having two identical alleles for a trait.
Detailed explanation-5: -Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism.
