Question

Which stage of human reproduction involves the fusion of sperm and egg to form a zygote?

Options

• Implantation

• Fertilisation

• Insemination

• Gestation

Answer 1

Fertilisation is the stage where the sperm and egg fuse together to form a zygote. This is the critical step in sexual reproduction where genetic material from both parents combines. This stage follows insemination (sperm transfer) and precedes implantation (attachment to the uterine wall).
