Hybrid (biology) 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, species or genera through sexual reproduction.
Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. Previously, reproductive isolation between two species and their parents was thought to be particularly difficult to achieve, and thus hybrid species were thought to be very rare.

De-extinction (also known as resurrection biology, or species revivalism) is the process of generating an organism that either resembles or is an extinct species. [1] There are several ways to carry out the process of de-extinction. Cloning is the most widely proposed method, although genome editing and selective breeding have also been considered.
Aug 4, 2021 · Repeated hybrid incompatibilities in Xiphophorus. Classic models in evolutionary biology predict that incompatibilities can arise between any pair of interacting genes. Recent empirical work has suggested that certain genes or pathways may be especially prone to becoming involved in hybrid incompatibilities.

A "Zeedonk," a zebra/donkey hybrid. In biology, a hybrid is the offspring of individuals of different taxonomic groups or, in another sense, an offspring of crosses between populations, breeds, or cultivars within a single species . In the first sense of the term, a hybrid is the result of interbreeding between two animals or plants of ...
Aug 4, 2021 · These findings have spurred interest in the genomic consequences of hybridization. Some of this genetic exchange reflects the process of adaptive introgression, which has been well-documented in several species ( Marques et al., 2019; Hedrick, 2013; Racimo et al., 2015 ). However, the introgression of adaptive and neutral variants occurs ...
