Question

Plse give brief and simple explanations of
1. Genetic variation.
2.natural selection
3.reproductive isolation.

Answer 1

Genetic variation means that biological systems – individuals and populations – are different over space. Each gene pool includes various alleles of genes.

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

Answer 2

Thus so
Genetic drift
- it is the sudden frequency of genes

Natural selection
- selection of a particular type of an organism for the beneficial for survival

Reproductive isolation
- it interrupts the flow of genes through gamets .
