Males are mentioned to be hemizygous, because they have only one allele for any X-linked characteristic. Males are said to be hemizygous because they’ve only one allele for any X-linked characteristic; males will exhibit the trait of any gene on the X-chromosome no matter dominance and recessiveness. With regard to Drosophila eye colour, when the P1 male expresses the white-eye phenotype and the feminine is homozygous pink-eyed, all members of the F1 era exhibit red eyes. The F1 era would exhibit only heterozygous purple-eyed females (XWXw) and solely white-eyed males (XwY). In people, biological sex is decided by a pair of intercourse chromosomes: XX in females and XY in males. The Y chromosome contains a small area of similarity to the X chromosome so that they’ll pair during meiosis, but the Y is far shorter and accommodates fewer genes.
