What are germ cell mutations?

Answer 1

A germ cell mutation is any detectable and heritable variation in the lineage of germ cells.
The presence of an altered gene within the egg and sperm (germ cell) such that the altered gene can be passed to subsequent generations.

Mutations in these cells are transmitted to offspring, while, on the other hand, those in somatic cells are not.

A germ cell mutation gives rise to a constitutional mutation in the offspring, that is, a mutation that is present in virtually every cell.

An example of a chromosome mutation in a sex cell would be trisomy 21 (aka downs syndrome), where a sex cell has an extra chromosome due to a homologous pair of chromosomes failing to separate during meiosis.

Germ cell mutations occur in reproductive cells (sperm or egg) and can be passed to offspring. They affect the individual's entire organism and may lead to hereditary conditions.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
