Q

How does a woman get pregnant?

A

Fertilisation takes place in oviduct; this is when haploid sperm & haploid egg nuclei fuse to form a zygote

17
Q

What is meant by the term haploid?

A

Ova and sperm cells are haploid, as they have half the normal number of chromosomes, 23 each, so that when they fuse they restore the full number of 46 in the zygote

18
Q

What happens after fertilisation?

A

Egg divides many times to form ball of cells called zygote

Travels along oviduct to uterus, where it will implant
