Answer 1

Answer:

Hybrids between closely related species are often inviable or, if they live, they are sterile. This hybrid inviability and sterility, collectively known as hybrid incompatibility, can reduce the exchange of genetic variants between species. Thus, hybrid incompatibility can be important in the process of speciation by acting as a reproductive isolating barrier (Coyne & Orr, 2004). Hybrid incompatibility, as a phenotype, is unusual, as it serves no apparent function and yet is so common. Naturalists and philosophers since Aristotle have been puzzled by its existence. Charles Darwin argued that hybrid incompatibility does not evolve because of direct natural selection for hybrid incompatibility, but is instead a by-product of other evolutionary divergence between the species (Darwin, 1859). Contemporary studies have confirmed Darwin's insight.
