Can males be heterozygous?
Females (XX) have two copies of each gene on the X chromosome, so they can be heterozygous or homozygous for a given allele. However, males (XY) will express all the alleles present on the single X chromosome that they receive from their mother, and concepts such as ‘dominant’ or ‘recessive’ are irrelevant.
Why are males Hemizygous?
Males are said to be “hemizygous” for any X-chromosome genes, meaning that there are only half (“hemi”) as many alleles as normally present for a diploid individual. As a consequence, if males (but not females) inherit an X-linked recessive trait from their mothers, they display the recessive phenotype.
