Re: Genes in the same linkage group are inherited together?

A centimorgan is the distance between two loci where the frequency of a crossover between the two loci per generation is 0.01. So the frequency of crossover between two genes 1.5 cM apart will be 0.015, and the frequency of a crossover between genes 140 cM apart will be 1.4. The alleles of the all g...

Genes in the same linkage group are inherited together?

... Thanks for your post! So those 43 genes (alleles of them) in the same linkage group are inherited together. But how likely are they inherited together? I know this is hard ...

... are ("tightly linked" and "close map distance" are pretty much synonymous). "the closer genes are within the same linakge group, the more likely they are inherited together?" Yes.

Genes in the same linkage group are inherited together?

... in a particular gene. Wang et al. (2009) found that the gene is in some linkage group that contains 43 genes ( http://genomebiology.com/2009/10/11/r126 ). When you ...
