Question

Describe the various steps involved in the sexual reproduction in animals. Draw labelled diagrams to show the fertilisation of an ovum (or egg) by a sperm to form a zygote

Answer 1

The various steps involved in the sexual reproduction in animals are as follows:

• Male gametes called sperms are produced by the male parent.
• Female gametes called eggs are produced by the female parent.
• The sperm fuses with the egg to form zygote. This process is termed as fertilisation.
• The zygote divides repeatedly to form a large number of cells. Ultimately it grows and develops into a baby
