Sagot :

The child would be born with twice as many chromosomes as it should. The organism's somatic cells are diploid (2n). This indicates that they have n double chromosomes.

  • Gametes (egg and sperm cells) are haploid cells, which means they contain n fewer chromosomes than other cells.
  • A diploid zygote (2n) is created when haploid egg cell (n) and haploid sperm cell (n) combine:

n + n = 2n

Consequently, the freshly created organism's somatic cells are diploid once more (2n).

  • Imagine a scenario where the gametes are diploid rather than haploid (n) (2n). A tetraploid zygote (4n) would result from the union of a diploid egg cell (2n) and a diploid sperm cell (2n):

2n + 2n = 4n

The offspring will have twice as many chromosomes as they normally would. The result is that the baby would have twice as many chromosomes as it should have if the gametes were not haploid.
