Class 12 NEET Biology Principles of Inheritance and Variation Questions Part 1

Sex influenced traits are autosomal traits that are influenced by sex. If a male has one recessive allele, he will show that trait, but it will take two recessive alleles for the female to show that same trait e.g. pattern baldness, moustaches and beard in males. Sex linked traits are those traits determining genes of which are found on the sex chromosomes. Sex limited traits are the traits which are expressed in a particular sex though their genes also occur in the other sex e.g., milk secretion in mammalian females.
