Human genetic disease - Human genetic disease - Sex-linked inheritance: In humans, there are hundreds of genes located on the X chromosome that have no counterpart on the Y chromosome.

  • Sex-Linked Traits Remember that humans have 23 pairs of chromosomes and that the 23rd pair are the sex chromosomes. Females are XX and males are XY. The traits found on the 23rd X chromosome are called X-linked traits. If an X-linked trait is recessive, females have a 1 in 3 chance of inheriting that trait. Males have a 1 in. Pedigree 1: A sex-linked recessive character. It mainly affects the males. The gene skips generation. Criss-cross inheritance is seen. Pedigree 2: It is an autosomal dominant character. It affects male and female equally. The gene expresses itself in each generation. Pedigree 3: It is an autosomal recessive character. The gene skips generation.
