Question

Why did hereditary posts prove to be disadvantageous sometimes?

Answer 1

Thanks for the question!!!

The mechanism by which variations are created and inherited is known as HEREDITY. Hereditary features are those traits which are passed on from one generation to another and are responsible for similar characteristics  from the parents to the offsprings. Gene can be regarded as a unit of heredity, a part of DNA and a unit of mutation. The gene carries these traits and the DNA is the genetic material.DNA is the abbreviated form of deoxy ribonucleic acid.
