A kind of breeding in which the parents with a particular phenotype produce offspring only with the same phenotype. Supplement A true breeding is a kind of breeding wherein the parents would produce offspring that would carry the same phenotype. This means that the parents are homozygous for eve...
Such types are also known as ‘pure-breeding’ and were, for example, used by MENDEL in his experiments with the garden pea. In more precise terms, parents breed true when they are homozygous (see HOMOZYGOTE for a pair of ALLELES of a particular gene. Collins Dictionary of Biology, 3rd...

This is a young male. He was only about 2.5m in length. This is a female of breeding age. She is regulating her body temperature by entering the water, and gaping her mouth to the wind. There are many blood vessels in the roof of the mouth and this cools the blood going to her b...
After humans and Neandertals met many thousands of years ago, the two species began interbreeding. While Neandertals aren’t around anymore, about two percent of the DNA in non-African people living today comes from them. Recent studies have shown that some of those Neandertal genes ...
decisions of taxonomists to assess the value of protected areas or the allocation of resources for conservation, describing and raising species based on insufficient data can also be a waste of resources and additionally lead to false decisions concerning captive or natural breeding for conservation ...
(iv) the impact of polyandry on the evolution of sperm storage organs and strategic ejaculation, body size, call structure, and anuran diversity. Our review has a strong focus on work on the Australian Myobatrachid frog,Crinia georgiana, as the breeding biology of this species, including ...
some have raised concerns about the use of genetic rescue, as it could lead to harmful effects, including the loss of local adaptive variation or genetic distinctiveness (genetic swamping) or poor outcomes for the transplanted individuals due to the lack of local adaptation (outbreeding depression...
