Preferred term

hemizygous  

Definition

  • A cell or organism is hemizygous at a locus (a fixed position on a chromosome, such as the position of a gene) if it possesses only one allele for a given trait. In humans, males are hemizygous for alleles expressed on the sex chromosomes as they have only one of each. [Source: Encyclopedia of Global Health; Hemizygous]
