... Mexico. All these asexual species appear to have arisen through the hybridization
of two or three of the sexual species in the genus. The mechanism by ... can lead to parthenogenetic reproduction is unknown. Because multiple hybridization
events can occur, individual parthenogenetic whiptail species can consist ...
... They can be "hybrids" produced through crossover (a form of genetic recombination ) of chromosomes, something that takes place in meiosis. This hybridization
has a random element and the chromosomes tend to be a little different in every gamete an individual produces. This recombination, and the fact that ...

While these numbers come from various secondary sources, the data may have originated from measures of DNA-DNA hybridization
or from direct sequence comparisons.

... therefore were not influenced by the environment. This simple test gave birth to the idea of heredity.
Mendel read his paper, Experiments on Plant hybridization
, at two meetings of the Natural History Society of Brunn in Bohemia in 1865 . When Mendel's paper was published in 1866 in Proceedings of the ...
... or varieties of organisms.
In molecular biology hybridisation is the process of joining two complementary strands of DNA.
In chemistry , hybridization
is the mixing of atomic orbitals to form new orbitals suitable for bonding.
... the same gene (described as allozymes ).
Isozymes are usually the result of gene duplication , but can also arise from polyploidisation or hybridization
. Over evolutionary time, if the function of the new variant remains identical to the original, then it is likely that one or the other will be ...
... pair, carrying different amounts of a set of fluorescent dyes, are hybridized to the chromosomes in a technique known as fluorescent in situ hybridization
(FISH). This gives each chromosome pair unique spectral characteristics due to the relative amount of each of the fluorochromes. Chromosomes can be ...
... which later became known as Mendel's Laws of Heredity or Mendelian inheritance . These are described in his paper " Experiments on Plant hybridization
" that was read to the Natural History Society of Brunn on February 8 and March 8, 1865 , and was published in 1866 .

By their very nature, phylogenetic trees hide any hybridization
and lateral gene transfer (Woese 2002) that may have taken place. For these reasons, the proposed PhyloCode (see External Link below) does not ...
... similar groups of organisms are "potentially" capable of interbreeding. Further, there is considerable variation in the degree to which hybridization
may succeed under natural and experimental conditions, or even in the degree to which some organisms use sexual reproduction between individuals to ...
