Answer:
♦Total number of chromosomes (stock and number of scion combined)(2n) = 56 + 24 = 80
♦ We know that the root contains the same number of chromosomes as the body cell, so the root contains 80 chromosomes.
♦We know that the ovum contains half the number of chromosomes in the body cell, so the number of ovum chromosomes = 80/2 = 40 chromosomes.
2n=80
Finally,n=40
