Quizplus · Accepted Answer

A tetraploid species has four sets of chromosomes. Therefore, the germ cell line would have 48 x 4 = 192 chromosomes. Each gamete would have half of the chromosomes, so 192/2 = 96 chromosomes per gamete. Since the question is asking for the number of chromosomes in each cell of the germ cell line, the answer would be 96/4 = 24 chromosomes.
