Of the following given choices;
A. growth
B. production of egg and sperm cells
C. reproduction of bacteria and unicellular protists
D. repair of damaged tissues\
The answer is; B
The genome of the pre-gamete cell in the gonads is halved by meiosis in the formation of gametes. Each pre-gamete cell produces 4 gametes. The reasons sperms and egg have half the genetic material is because they will need to fuse (during fertilization) with the other gamete from the other parent to form a zygote with the full genetic makeup.
