  • A phenotypic characteristic or trait such as male pattern baldness that is expressed differently in males and females, usually because its expression depends on androgens or oestrogens, and that is controlled by a single gene that is dominant in males but recessive in females, so that, for example, men who inherit the gene from either parent lose hair as they age, whereas women do so only if they inherit it from both parents and are thus homozygotes.
  • They are traits that their genes are carried on autosomes and the sex of individual acts to modify their dominance where the act of these genes is influenced by the hormones secreted from gonads of adult males and females , Sometimes, the sex of living organism acts to modify the dominance of some traits that are called sex-influenced traits, such as the presence of horns in cattle trait and genetic baldness trait in humans.
