Question

Explain how, characteristics (or traits) are inherited through genes.

Answer 1

• The characteristics or traits of parents are transmitted to their progeny through genes present on their chromosomes during the process of sexual reproduction.
• There is a pair of genesfor each characteristics of an organism.
• However, each parent passes only one of the two genes of the pir for each characteristics to its progeny through gamete. Thus, the male gamete and female gamete carry one gene for each characteristics from the gene pairs of parents.
• During fertilisation, they fuse and form zygote. This zygote grows and develops to form a new organism having characteristics from both the parents.
