Genetic pollution: The great genetic scandal. In Oenothera lamarchiana the diploid species has 14 chromosomes, this species has spontaneously given rise to plants with 28 chromosomes that have been given the name Oenthera gigas.
However, fertility in female mules has been reported with a donkey as the father (McBeath 1988). Thus, species are generally recognized as distinct, fully…, The mint family (Labiatae or Lamiaceae) is a large group of dicotyledonous plants occurring worldwide in all types of climates except in extreme arct…, Legumes or beans are species of plants in the family Fabaceae (also known as Leguminoseae). A Dictionary of Plant Sciences.  Intergeneric hybrids result from matings between different genera, such as between sheep and goats.
Example of an animal hybrid is a mule.  Plant breeders use several techniques to produce hybrids, including line breeding and the formation of complex hybrids. Analyzing the genomes of 600 Europeans and East Asians found that combining them covered 20% of the Neanderthal genome that is in the modern human population.
." Encyclopedia.com. There is a similar situation with White-headed Ducks and Ruddy Ducks.
(It is reported that the black kite (the male) refused female black kites but mated with two female red kites. However, fertility in female mules has been reported with a donkey as the father. In 2010, the Neanderthal genome project showed that 1–4% of DNA from all people living today, apart from most Sub-Saharan Africans, is of Neanderthal heritage. "Transgressive segregation, adaptation and speciation".
." Hybrids are bred to improve the characteristics of the resulting plants, such as better yield, greater uniformity, improved color, disease… … Wikipedia, hybrid Ab — Artificially produced antibody made by fusing hybridomas producing two different antibodies; the hybrid cells produce three different antibodies, only one of which is a heterophile antibody.
. In many groups of plants hybridization has been used to produce larger and more showy flowers and new flower colors. MICHAEL ALLABY "hybrid  This is allowing another kind of hybridization that is more of the focus of conservation genetics to occur: anthropogenic hybridization. The term hybrid, therefore, has a wider application than the terms mongrel or crossbreed, which usually refer to animals or plants resulting from a cross between two races, breeds, strains, or varieties of the same species. Hybrid (particle physics), a valence quark-antiquark pair and one or more gluons Dog hybrids are crosses between different breeds and are often bred selectively. Other times, a wild species will come into an area inhabited by a domesticated species.
Hybrids between black rhinos and white rhinos have been recognized.  Most leave it as a case-by-case basis, depending on detecting of hybrids within the group. https://www.encyclopedia.com/environment/encyclopedias-almanacs-transcripts-and-maps/hybrid, "hybrid ." Usually the typical chromosome number is doubled in successful allopolyploid species, with four sets of chromosomes the genotypes can sort out to form a complete diploid set from the parent species, thus they can produce fertile offspring that can mate and reproduce with each other but can not back-cross with the parent species.
The domestic. One such flower, Oenothera lamarckiana, was central to early genetics research into mutationism and polyploidy.
In this way, habitat fragmentation is essentially an indirect method of introducing species to an area. (October 16, 2020).
In Britain, there is hybridization of native European red deer and introduced Chinese sika deer. . Newer, genetically engineered (GE) varieties are be a problem for local biodiversity. In the first sense of the term, a hybrid is the result of interbreeding between two animals or plants of different taxa, whether between individuals belonging to different species within the same genus (interspecific hybrids or crosses), different subspecies within the same species (intraspecific hybrids), or different genera (intergeneric hybrids). Autopolyploidy resulting from the sudden multiplication in the number of chromosomes in typical normal populations caused by unsuccessful separation of the chromosomes during meiosis. , Cagebird breeders sometimes breed bird hybrids known as mules between species of finch, such as goldfinch × canary.
Harpy - the torso of a woman with the wings and feet of a bird. The manticore portrays the bestial and vicious nature of humans. Double cross hybrids result from the cross between two different F1 hybrids (i.e., there are four unrelated grandparents).
