Category:Hybrid

In biology and specifically, genetics, the term hybrid has several meanings, all referring to the offspring of sexual reproduction.
 * 1) In general usage, hybrid is synonymous with heterozygous: any offspring resulting from the mating of two distinctly homozygous individuals
 * 2) a genetic hybrid carries two different alleles of the same gene
 * 3) a structural hybrid results from the fusion of gametes that have differing structure in at least one chromosome, as a result of structural abnormalities
 * 4) a numerical hybrid results from the fusion of gametes having different haploid numbers of chromosomes
 * 5) a permanent hybrid is a situation where only the heterozygous genotype occurs, because all homozygous combinations are lethal.
