Question

According to the law of independent assortment, what is the possible number of combinations that chromosomes can assort to independently in the gamete?

Options
  • A

    16,777,216

  • B

    2,0,48

  • C

    4,194,304

  • D

    8,388,608

Explanation

According to the law of independent assortment, there are 2n combinations where chromosomes can assort into different gametes. So where n is the haploid number, you get 223=8,388,608. There are 8,388,608 possible combinations of chromosomes when assorting into gametes. Therefore, option D is correct.

This option is incorrect. According to the law of independent assortment, there are 2n combinations where chromosomes can assort into different gametes. So where n is the haploid number, you get 223=8,388,608. There are 8,388,608 possible combinations of chromosomes when assorting into gametes. Therefore, option D is correct.
