Mutations in which type of cells can be inherited by future generations?

Mutations that occur in germ cells, which include sperm and egg cells, can be passed on to offspring. This is because germ cells are involved in reproduction; when they combine during fertilization, any genetic changes present in these cells are transmitted to the next generation. This can lead to inherited traits or diseases, which may manifest in the offspring.

In contrast, mutations in somatic cells—such as brain cells, skin cells, and nerve cells—do not have this capability. These mutations affect only the individual and are not passed down to future generations. Somatic cells are not involved in the reproductive process, so any changes within these cells will not impact genetic inheritance. This distinction is crucial for understanding how genetic information is transmitted and the implications of genetic mutations in both individuals and populations.
