WebWith both an X and a Y-chromosome, males inherit both X and Y-linked traits, while females only inherit X-linked traits. Since males have only one copy of each sex chromosome, they are hemizygous for all sex-linked genes, and they always express the phenotype * of the allele * they get. In other words, their phenotypes always match their … WebRe-evaluation of Mendelian inheritance patterns of markers unassigned to any mapping parent according to hemizygous segregation patterns (models presented) identified matches for many of these markers to hemizygous patterns. The greatest proportion of these markers assigned to SL15 (Nincreased to 574).

WebAs is illustrated in the two pedigrees of Fig. 5, the hallmark of XL inheritance is the absence of male-to-male transmission. A heterozygous female has a 50% chance of transmitting the mutation to a son or a daughter, whereas a hemizygous male transmits the mutation to all his daughters but not to his sons.
