If skewed X inactivation were the explanation for the expression of this nystagmus, one might expect that they would exhibit deuteranomaly by the same mechanism. Mouse genomic variation and its effect on phenotypes and gene regulation. It uses the concept of the expected number of alleles shared identity by decent IBD between affected sib pairs dependent on the sex of the sib pair.

However, the probability of sharing 0 or 1 alleles IBD from the paternal side depends on the male recombination fraction between the locus and the X-specific region and on the sex of the sib pair. Mei L. We review existing tools like genetic and physical maps, linkage disequilibrium methods, linkage and association analysis, implemented statistical methods, and their suitability for PARs.
Sex, not genotype, determines recombination levels in mice.
It can be performed with every linkage program able to handle sex-specific genetic maps. Sex, not genotype, determines recombination levels in mice. The normal color vision in these women suggests that other mechanisms are responsible for the variable penetrance of the nystagmus-causing mutation in heterozygotes.
A mouse speciation gene encodes a meiotic histone H3 methyltransferase.
