Genetic map

Definition

noun

(1) A list of ordered genetic loci for a particular genome.

(2) A map of the relative positions of genetic markers along a chromosome of a particular species as determined by the recombination frequency during crossover of homologous chromosomes.


Supplement

Genetic linkage map shows the relative positions of genetic markers on a chromosome. The positions of genetic markers are determined based on how often the loci are inherited together rather than on the specific physical distance between them. It means that the more often the two genetic markers are inherited together the farther apart they are. In contrast, the lower frequency of being inherited together the closer the smaller the physical distance is between them.

Genetic map units are measured in terms of centimorgans (cM).


Synonym: linkage map.
Compare: gene map.
See also: genetic locus, genetic marker.

In isogamous organisms we have a small genetic differentiation between the gametes, as the + and - one I said. Is there an organism like this in nature? Also, is there any isogamous organism ...

Re: Is talent inherited?

... inherited, being the brain raw structure stored in the DNA. Completely false! Do you realize that according to what you are saying, autism is not genetic and we know that it is? Do you realize that what you call "cerebral health" is determined by genetics?
