hemizygousthe condition of having only one set of
alleles instead of two, as in the case of
loci on the X
chromosome in males

gene for a particular
trait in a
diploid organism, the
organism is
hemizygous for that
trait, and will display a
recessive phenotype.

sex-linked, the heterogametic sex (e.g.,
human males) have only one copy of the
