Experiments on Plant Hybridization" (German: Versuche über Pflanzen-Hybriden) is a seminal paper written in 1865 and published in 1866 [1] [2] by Gregor Mendel, an Augustinian friar considered to be the founder of modern genetics. The paper was the result after years spent studying genetic traits in Pisum sativum, the pea plant.
Human activities such as movement of species and modification of landscape can result in genetic pollution, hybridization, introgression and genetic swamping. These processes can lead to homogenization or replacement of local genotypes as a result of either a numerical and/or fitness advantage of introduced plant or animal. [19]
Rusa is a genus of deer from southern Asia. They have traditionally been included in Cervus, and genetic evidence suggests this may be more appropriate than their present placement in a separate genus.

Hybrid between red-eared slider and Ouachita map turtle. Genus Trachemys. Species T. scripta. The hybrid between a red-eared slider and a yellow-bellied slider. Class Mammalia. Clade Euungulata ...
The first uses of test crosses were in Gregor Mendel’s experiments in plant hybridization.While studying the inheritance of dominant and recessive traits in pea plants, he explains that the “signification” (now termed zygosity) of an individual for a dominant trait is determined by the expression patterns of the following generation.
Skull of a red deer. The red deer is the fourth-largest extant deer species, behind the moose, elk, and sambar deer.It is a ruminant, eating its food in two stages and having an even number of toes on each hoof, like camels, goats, and cattle.

In genomics, DNA–DNA hybridization is a molecular biology technique that measures the degree of genetic similarity between DNA sequences. It is used to determine the genetic distance between two organisms and has been used extensively in phylogeny and taxonomy .
