What is a germ cell?
Options
- AA cell that generates gametes in sexually reproducing organisms
- BA cell that generates somatic cells
- CA cell that does not have any mutations
- DA cell that has undergone somatic mutations
Correct answer
A. A cell that generates gametes in sexually reproducing organisms
Step-by-step solution
As polymorphism in DNA sequence is the basis of genetic mapping of human genome as well as of DNA fingerprinting, it is essential that we understand what DNA polymorphism means in simple terms. Polymorphism (variation at genetic level) arises due to mutations. New mutations may arise in an individual either in somatic cells or in the germ cells (cells that generate gametes in sexually reproducing organisms) . If a germ cell mutation does not seriously impair an individual's ability to have offspring who can transmi
