Biochemical stress is another factor fire
The mutation in the somatic cells is known as somatic mutations. As they do not take place in the cells, which give rise to gametes, thus, the mutation is not inherited to the next generation by the sexual means.
On the other hand, the genetic mutations take place in the germline cells, that is, egg and sperm, because of this the mutations possesses the tendency to get passed on from one generation to another.
Thus, mutations are only passed on to offspring when they take place in germ cell DNA. The other kind of cells, the somatic cells refers to the rest of the cells in the body and mutations, which takes place in these cells do not get inherited further to the offspring.
Hence, the correct statements are mutations to gametes can be passed on to an organism's offspring and mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Answer:
An egg or sperm only has half of the parent's sex chromosome pair. An egg will always have an X chromosome, since the woman's sex chromosome pair only has Xs. Sperm can have either an X chromosome or a Y chromosome. If a sperm with an X chromosome fertilizes the egg, the new cell will have two X chromosomes. One came from the father's sperm and one came from the mother's egg. Since the sex chromosome that is made is XX, the cell will grow into a girl baby.

<span>The hypothesis of microspheres builds off of the RNA world hypothesis. If RNA molecules could self-replicate, it would mean that whenever a microsphere split, the early genetic coding in the RNA would pass to the newly formed microspheres</span>
100% or all the males will express mutant allele.
Human X and Y chromosomes, with XX indicating female and XY indicating male, establish a person's biological sex. The Y chromosome is substantially shorter and has a lot less number of genes than the X chromosome, but they do share a minor region of similarity that allows them to mate during meiosis.
What is X-linked ineheritance:
- A pair of sex chromosomes—XY in men and XX in females—determine biological sex in humans and other mammals.
- X-linked genes are those that are found on the X chromosome. Males and females (XX) have different numbers of X-linked genes, which results in distinct inheritance patterns (XY).
- Due to the X-linked inheritance pattern, X-linked human genetic disorders are much more prevalent in males than in females.
