An ovarian tumor in a 21-year-old woman is genotyped and a gain-of-function mutation is found on the X chromosome that was not present in cells taken from a biopsy of her uterus. She is concerned about her future potential children and asks a genetic counselor what the likelihood is that this mutation will be passed along to her children. What is the correct answer

Respuesta :

Only tumor cells had the mutation, indicating that it was a somatic one. No children of hers will inherit this mutation because somatic mutations cannot be passed on to offspring.

  • Germ cells are the only cells that are transmitted from parents to children (Egg and sperm).
  • Somatic cells are not inherited. Therefore, there is no way for a somatic cell mutation to be passed on to progeny.
  • If the mutation is in an egg or sperm cell, the kids exactly inherit the mutation.
  • Here, Only tumor cells had the mutation, indicating that it was a somatic one. Thus, No children of hers will inherit this mutation.
  • For single-celled organisms that lack germ or somatic cells, for example, mutations are passed on when a new half of the organism divides to reproduce.
  • Mutations can be conveyed via the plasmids in cells that use them to pass genetic information to other single cells, etc.

The mutation was only present in tumor cells, proving that it was a somatic mutation. She will not convey this mutation to any of her children because somatic mutations cannot be passed from parent to child.

What is somatic mutation?

Any mutation that happens in a cell other than a gamete, germ cell, or gametocyte is referred to as a somatic mutation because it involves a change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells.

The only cells that are passed from parents to children are germ cells (egg and sperm).

It is impossible to inherit somatic cells. Therefore, a somatic cell mutation cannot be passed on to offspring.

When a mutation occurs in an egg or sperm cell, it is completely passed on to the offspring.

Here, the mutation was present only in tumor cells, proving that it was a somatic mutation. None of her offspring will therefore carry this trait.

For example, when a new half of a single-celled organism divides to reproduce, mutations are passed on because these organisms lack germ or somatic cells.

The plasmids that cells utilize to transmit genetic information to other single cells, etc., can also transmit mutations.
