Genetic map function. In genetics, mapping functions are used to model the relationship between map distance (measured in map units or centimorgans) between markers and recombination frequency between markers. One utility of this is that it allows values to be obtained for genetic distances, which is typically not estimable, from recombination ...
Figure 1: Genetic distance map by Cavalli-Sforza et al. (1994) [1] Genetic distance is a measure of the genetic divergence between species or between populations within a species, whether the distance measures time from common ancestor or degree of differentiation. [2] Populations with many similar alleles have small genetic distances.
Equine coat color genetics determine a horse 's coat color. Many colors are possible, but all variations are produced by changes in only a few genes. Bay is the most common color of horse, [ 2] followed by black and chestnut. A change at the agouti locus is capable of turning bay to black, while a mutation at the extension locus can turn bay or ...
A black coat. Black: Black is relatively uncommon, though it is not "rare". There may be two types of black, fading black and non-fading black. Many, though not all black horses will fade to a brownish color if the horse is exposed to sunlight regularly. This may be due to nutrition or genetics.
Pedigree chart. A pedigree chart is a diagram that shows the occurrence and appearance of phenotypes [jargon] of a particular gene or organism and its ancestors from one generation to the next, [1] [2] [3] [unreliable source?] most commonly humans, show dogs, and race horses .

Centimorgan. In genetics, a centimorgan (abbreviated cM) or map unit ( m.u.) is a unit for measuring genetic linkage. It is defined as the distance between chromosome positions (also termed loci or markers) for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01.
Antron Brown, 48, has 75 career Top Fuel victories, winning titles in 2012, 2015 and 2016. Matt Hagan, 41, picked up his 50th Funny Car victory in April and the reigning champ was nominated as ...
