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.
Hybrid dysgenesis is caused by the mobilization of Drosophila. melanogaster P elements. P elements move at a high frequency in the germlines of the progeny. of certain crosses causing new mutations and sterility. Crosses. between different Drosophila melanogaster strains from different parts. of the world produce normal, fertile progeny.
