Why do diploid organisms need to have specialized sex cells? sex cells (gametes - sperm & egg) allow traits to be combined from two organisms; (if all 46 chromosomes were combined from both parents, that would equal 92 chromosomes, which is way too many - taking half from each is the best way to go).
