If a normal human cell has 46 chromosomes, how many chromosomes will be there in a human (i) sperm cell, and (ii) zygote?
(A) (i) sperm cell will have 23 chromosomes as gametes consist of half the number of chromosome of somatic cells.
(ii) Zygote will have 46 chromosomes as 23 chromosomes from the gamete of mother (egg) and 23 chromosome from the gamete of the father (sperm) will fuse to a total of 46 chromosomes.
