Question

WHAT ROLE IS PLAYED BY GENE MUTATION,GENETIC RECOMBINATION AND CHROMOSOMAL ABBERATIONS IN EVOLUTION

Answer 1

Explanation:

Mutation:

A mutation is change in DNA ,the herreditary material of life.An organisms DNA affects how it looks,how it behaves and its physiology. so a change in organisms in DNA can cause changes in all aspects of life.

Genetic Recombinations:

Genetic recombinations is also known as genetic reshuffling.It is the exchange of genetic material between different organisms which leads to production of offspring with combination of traits that differ from those found in either parent.

Chromosomal abberation:

A chromosomal disorder,anomally,abberation or mutation is missing ,extra or irregular portion of chromosomal DNA. It can be form in typical no. of chromosomes or a structural abnormality in one or more chromosomes.They can be organised into two basic groups, numericals and structural anomalies.
