A mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.
For a hybrid form to persist, it must be able to exploit the available resources better than either parent species, which, in most cases, it will have to compete with.For example: while grizzly bears and polar bears may be able to mate and produce offspring, a grizzly–polar bear hybrid is apparently less- suited in either of the parents' ecological niches than the original parent species ...
[5] Family Boidae. Hybrids between Columbian boa and yellow anaconda. Genus Corallus. Hybrid between emerald tree boa and Amazon tree boa. Family Colubridae. A fertile cross between a king snake and a corn snake. One example is a cross between a California kingsnake and a corn snake called the "jungle corn snake." [6] [7] Genus Lampropeltis
The hybridization of macaws in the wild is less common than in captivity due to natural barriers and mating behaviors, although a few rare cases have been recorded. One example was the natural hybridization of a Spix's and Illiger's macaw recorded in Conservation Genetics (2001), which demonstrated two species of macaws producing offspring ...
This polymorphic trait has a direct effect on mate choice and mating behavior; as shown in laboratory mating tests that opposite-coil pairs mate much less often. [48] In areas where P. suturalis lives sympatrically with other sinistral and dextral Partula species, the opposite P. suturalis morph is typically present. [ 9 ]
Hybrid incompatibility is a phenomenon in plants and animals, wherein offspring produced by the mating of two different species or populations have reduced viability and/or are less able to reproduce. Examples of hybrids include mules and ligers from the animal world, and subspecies of the Asian rice crop Oryza sativa from the plant world ...
It is characterized by a "selective response by animals to particular stimuli" which can be observed as behavior. [1] In other words, before an animal engages with a potential mate, they first evaluate various aspects of that mate which are indicative of quality—such as the resources or phenotypes they have—and evaluate whether or not those ...
(1) mating traits are identified in the focal species; (2) mating traits are affected by a species interaction, such that selection on mating traits is likely; (3) species interactions differ among populations (present vs. absent, or different species interactions affecting mating traits in each population); (4) mating traits (signal and/or ...
