PATHOLOGY

Detailed explanation-1: -A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus. Therefore, a dihybrid organism is one that is heterozygous at two different genetic loci.

Detailed explanation-2: -Heterozygous, as related to genetics, refers to having inherited different versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is heterozygous for a genomic marker has two different versions of that marker.

Detailed explanation-3: -One allele for every gene in an organism is inherited from each of that organism’s parents. In some cases, both parents provide the same allele of a given gene, and the offspring is referred to as homozygous ("homo” meaning “same") for that allele.

Detailed explanation-4: -The hybrid parents are heterozygous, meaning they have one of each allele (A and a, Dominant and Recessive).

Detailed explanation-5: -A genetic hybrid carries two different alleles of the same gene, where for instance one allele may code for a lighter coat colour than the other. A structural hybrid results from the fusion of gametes that have differing structure in at least one chromosome, as a result of structural abnormalities.
