Therefore the maxmimum distance that two genes can be apart and still measure that distance is just less that 50 cM. If two genes are greater than 50 cM apart, then we can not determine ... WebSex Linkage. Sex linkage applies to genes that are located on the sex chromosomes. These genes are considered sex-linked because their expression and inheritance patterns differ between males and females. While sex linkage is not the same as genetic linkage, sex-linked genes can be genetically linked (see bottom of page).
