Why is it important for gametes to be haploid?(1 point)
Responses

It is impossible for them to be diploid because reproduction does not result in diploidy.

When gametes are made, the diploid cell splits twice, creating four haploid organisms.

Neither parent has the full set of genetic information so each must contribute their half.

Because each gamete contributes one set of chromosomes, fertilization restores the species' normal (diploid) chromosome number; if gametes were diploid chromosome number would double each generation.
