Question

7. Write short note on the following:
a. Fertilisation
b. Unisexual organism
​

Answer 1

Answer:

•Fertilization is the fusion of haploid gametes, egg and sperm, to form the diploid zygote. Note though there can be subtle differences in the fertilization process which occurs naturally within the body or through reproductive technologies outside the body, the overall product in both cases is a diplod zygote.

•Unisexual organisms are those organisms which can only produce either male gamete or female gametes but never both. For example, human beings are the unisexual organisms as human beings are divided into male and female.

Answer 2

Fertilisation is the movement when a sperm and egg join together , and the genes from the mother and father combine to form a new life .
