Sex Determination and Sex-linked Genes

Sex Determination and Sex-linked Genes. Genes located on X or Y chromosomes behave differently than autosomal genes. Reciprocal crosses distinguish between sex-linked and autosomal genes. 1. Sexual Differences - Human Chromosomes. 2. Sexual Differences - Drosophila Chromosomes. 3.
