Zoology - Principles of Inheritance and Variation Question with Solution | TestHub

Sex-limited traits are traits that are visible only within one sex. Premature baldness and type of beard growth are human sex-limited characters. Sex linked traits are traits that are found on either one of the chromosomes that determine sex, or the sex chromosomes. Examples: haemophilia. Related Theory Genes that are located on the sex chromosomes are called as sex linked genes. Because $X$ and $Y$ chromosomes have different genes, sex-linked genes have a pattern of expression that is different from autosomal genes. Because males only have one copy of each type of sex chromosome. they express all of the alleles on both chromosomes. Sex-influenced traits are autosomal traits that are influenced by sex. One such gene is baldness.
