Help Please :) How many chromosomes should a cell used in sexual reproduction have?

- half as many as the species normally has in its diploid cells, so that the other chromosomes can come from the other parent

- exactly one chromosome, regardless of species, so that the offspring can develop its own genetic code and increase diversity

- exactly as many as the species normally has in its diploid cells, so that the offspring’s genetic code is the same as the parents'

- twice as many as the species normally has in its diploid cells, so the offspring will have all the traits from both parents
