Question

How do human beings reproduce?(5 marks)

Answer 1

Human beings reproduce when a pair of allosome from each of their body undergo meiosis.

Human males have XY chromosomes

And

Human females have XX chromosome

During the process of fertilisation both the chromosome fuse to form a zygote

The zygote develops into a blastocyst , at this time the blastocyst gets implanted in the endometrium wall

The zygote develops into a foetus and then into a baby

This period is called Gestation period
