sex linkage and recombination

• Recombination is a mechanism where the homologous pairs of chromosomes exchange genes.
• Human Chromosomes. The 1st to 22nd pairs are called the autosomes, and the 23rd pair is termed as the sex chromosome.
• Sex-linked inheritance refers to the inheritance of genes located on

  the sex chromosomes, typically the X chromosome in humans.
