Question

The figure below shows a single organism undergoing reproduction and the progeny with minor difference. What could be the reason for the variation?

A.

Errors in DNA copying

B.

Errors in RNA formation

C.

Errors in protein formation

D.

Gene being non – functional

Correct option is A

The correct Option is Ans A) Errors in DNA copying

The variation observed in the progeny of the organism undergoing reproduction could be due to genetic mutation or recombination processes.

·In Asexual Reproduction:

  • Genetic Mutations: During DNA replication, small random errors may occur, leading to minor genetic differences in the progeny.
  • Environmental Influence: External factors such as temperature, radiation, or chemicals can cause slight variations in genetic expression, even without changes in the DNA sequence.

·In Sexual Reproduction:

  • Recombination: During meiosis, genetic material is shuffled and recombined, leading to variations in the progeny.
  • Independent Assortment and Fertilization: Random combinations of parental chromosomes and gametes contribute to genetic diversity.
