Question

Which type of mutation occurs only in gametes?
germline mutation

somatic mutation

point mutation

frameshift mutation

Answer 1

Answer:

Germline mutation

Explanation:

A germline mutation is a genetic change produced in the gametic-germline cells (i.e., male and female gametocytes). The mutations in the germline are inherited in the next generation, while changes in somatic cells are not inherited. Moreover, the germline mutations may occur either before the fertilization or during embryonic development (zygote morula, blastula and gastrula). This type of mutation may be induced by both endogenous (e.g., oxidative DNA damage) and exogenous (e.g., exposure to UV light) factors.

Answer 2

The type of mutation that occurs in gametes only is : ( A ) Germline mutation

Germline mutation is a type of mutation that occurs in the gametocytes ( male and female ) and is passed( inherited ) on to the offspring ( next generation ). while mutations occurring in somatic cells are not passed on to the next generation .

Germline mutation is induced by either endogenous factors or exogenous factors and this is because Germline mutations can occur before fertilization or after fertilization.

Hence we can conclude that the type of mutation that occurs in gametes only is Germline mutation.
