Explanation:
Detailed explanation-1: -Each daughter cell will have 30 chromosomes.
Detailed explanation-2: -Solution : (a) 20 chromosomes, because in merosis cell dicison chromosome number becomes halved.
Detailed explanation-3: -A haploid cell of all organisms contains an unpaired set of chromosomes and half the number of chromosomes as a diploid cell, so the answer is 20 (half of 40).
Detailed explanation-4: -The correct answer: In a certain organism 2n=40. Sperm cells will have n=20 chromosomes. The organism has 40 chromosomes in the diploid cells in their body. Since the male gamete sperm is produced with the help of meiosis, therefore the chromosome number in the gamete is reduced to half in the gametes.
