Define the term hemizygous and explain how the hemizygous condition relates to sex-linked inheritance

What will be an ideal response?


Because males cannot be homozygous or heterozygous for genes on the X chromosome, males are said to be hemizygous for all genes on the X chromosome. Traits controlled by genes on the X chromosome are defined as dominant or recessive by their phenotype in females. Males give an X chromosome to all daughters and a Y chromosome to all sons. They never give an X chromosome to any of their sons.
