what are hybrid alleles
1 Hybrid generally refers to any offspring resulting from the breeding of two genetically distinct individuals, which usually will result in a high degree of heterozygosity, though hybrid and heterozygous are not, strictly speaking, synonymous. Extremely rare interfamilial hybrids have been known to occur (such as the guineafowl hybrids). 2  No interordinal (between different orders) animal hybrids are known. 3  The third type of hybrid consists of crosses between populations, breeds or cultivars within a single species.
