2 / 15

Fertilisation is the process of

Adhesion of male and female reproductive organs

The formation of gametes by a reproductive organ

3 / 15

The number of chromosomes in parents and offsprings of a particular species remains constant due to: Halving of chromosomes during gamete formation

Doubling of chromosomes after zygote formation

Halving of chromosomes during gamete formation

Doubling of chromosomes after gamete formation

Halving of chromosomes after gamate formation
