$\bullet$ Each cell has two copies of each chromosome one from male and other from female parent. (1 Mark)
$\bullet$ Each germ cell (gamete) takes one chromosome from each pair (either maternal or paternal). (1 Mark)
$\bullet$ When two germ cells(gamete) unite. They restore the normal number of chromosomes in the progeny ensuring the stability of DNA of the species. (1 Mark)
