Punnett Squares are very useful for tackling practice problems; remember to include X and Y to represent the X and Y chromosomes, … WebFemales have two X-chromosomes. Males have one X and one Y-chromosome. With 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 ...
