Question

Which of the following is the blastogenic variation?

• A. Germ cell variation
• B. Discontinuous variation
• C. Somatogenic variation
• D. Both A and B

Answer 1

Answer: (D)

Both A and B

There are changes that occur in the genes of the organism. These changes may be heritable. The changes may be due to an assortment of genes during meiosis in sexual reproduction or due to some sudden change in the composition of genes or chromosome number. An example of change due to meiosis is the difference in height of a population.

These include both continuous and discontinuous variation and germ cell variation ie take place in the gametes.

So, the correct option is 'Both A and B'.
