Respuesta :
A) 12 is the answer bc sex cells have half as many chromosomes as the offspring will have, half from the mother, the other half from the father.
Correct answer: A). 12
Sex cells are formed by the process of meiosis, and after the process of meiosis, the cell contains the half number of chromosomes as present in the parent. So if the parent has 24 pairs of the chromosome, then sex cells must contain 12 chromosomes, in order to form a diploid set of chromosomes after fertilization.
