Question

Why do we often look like our parents ?

Answer 1

Genes:

1. We look like our parents because the way we grow and develop is determined by genes.
2. Genes are present on the chromosomes which we receive from our parents in the egg and sperm.
3. The characteristics of individual human beings are passed from one generation to the next in their chromosomes.
4. Each of our parents gives us 23 chromosomes making 46 in all.
5. That means we have two versions of each of our genes, but one is often dominant.
6. We see the effect of the dominant gene but the other (recessive) gene is still there and can be passed on to our children.
