This is because sharks are pregnant for 6 months to 2 years. Which decreases shark population due to slow birth rates. This also effects female sharks health die to the stress of carrying many sharks for up to 2 years. Most sharks die before or after giving birth. Overfishing for sharks is rapidly decreasing the shark population due to slow breeding but many fisherman. Less females and males are able to mate and sharks are pregnant for so long that the female has a high percentage of getting caught. In the long run more and more sharks are being killed each year which decreases sharks population for obvious and non obvious reasons.

Explanation:

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
