F. Wei is a typical SPS, and has precious breeding values for its special flowering period. This study surveyed the age structure and spatial distribution of C. azalea, analyzed its genetic diversity and fine-scale spatial genetic structure (SGS) using microsatellite markers ...
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 ...
In some cases, the data are more directly connected to the cluster definition. In species delimitation, there may be interbreeding data, in which case researchers can specify the requirements of a clustering more directly. This may imply graph theoretic clustering methods and a specification of how...
(and explain) large-scale change. The first chapter of theOrigin of Species, for example, is mainly about pigeons because Darwin wanted to convince his readers of the validity of extrapolating from small changes produced by artificial breeding over short time intervals to larger changes produced ...

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...
