Sex cells will always contain half of the number of chromosomes needed for a being. So if a fishes sperm cell contains 12 chromosomes and the ovum also contains 12 chromosomes then when fused together they will have 24 chromosomes in total.

Two factors infuence the regions photosynthetic productivity which would be the amount of solar radiation and the availability of nutrients because solar radiation is needed as well as nutrients which keeps the plant healthy
