2. Drosophila hybrid sterility - Wikipedia

   en.wikipedia.org/wiki/Drosophila_hybrid_sterility

   In the off-spring of crosses between Drosophila simulans and its island derivative Drosophila mauritiana, female hybrids are fertile but male hybrids are sterile. Recent studies have shown that a critical gene for gender determination in Drosophila known as the sex-lethal gene is highly misregulated in D. melanogaster and D. simulans hybrids ...

3. Sterility (physiology) - Wikipedia

   en.wikipedia.org/wiki/Sterility_(physiology)

   Hybrid sterility can be caused by different closely related species breeding and producing offspring. These animals are usually sterile due to the different numbers of chromosomes between the two parents. The imbalance results in offspring that is viable but not fertile, as is the case with the mule.

4. List of genetic hybrids - Wikipedia

   en.wikipedia.org/wiki/List_of_genetic_hybrids

5. Haldane's rule - Wikipedia

   en.wikipedia.org/wiki/Haldane's_rule

   In humans, barring intersex conditions causing aneuploidy and other unusual states, it is the male that is heterogametic, with XY sex chromosomes.. Haldane's rule is an observation about the early stage of speciation, formulated in 1922 by the British evolutionary biologist J. B. S. Haldane, that states that if — in a species hybrid — only one sex is inviable or sterile, that sex is more ...

6. Hybrid incompatibility - Wikipedia

   en.wikipedia.org/wiki/Hybrid_incompatibility

   Hybrid incompatibility occurs when the offspring of two closely related species are not viable or suffer from infertility. Charles Darwin posited that hybrid incompatibility is not a product of natural selection, stating that the phenomenon is an outcome of the hybridizing species diverging, rather than something that is directly acted upon by selective pressures.
