Can somatic mutations occur in sex chromosomes?
No, they occur in the organism's body cells and cannot be inherited by the offspring .
Is it true that only mutations in gametes can be passed from parent to offspring?
Gametic mutations occur in the cells of the gonads (which produce sperm and eggs) and may be inherited. There are two types of mutations that can occur in gamete cells: 1. Gene Mutations 2. Chromosomal Mutations
What is somatic variation?
Mutations that occur in the somatic cells are called somatic variations .New mutations occur twice as frequently in sperm as in eggs(germ cells), probably because so many more cell divisions are required to make sperm than eggs.
How do mutations occur during mitosis?
reasorment of chromosomes can occur during meosis by crossing over
Which kind of mutation has the greater potential to affect the evolution of a population a mutation to a body cell or a mutation in an egg cell?
Mutations that occur during gametogenesis (formation of egg and sperm) are called germ-line mutations. They are more significant than somatic mutations (which occur in body cells) because they can be transmitted to the next generation whereas somatic mutations are not transmitted to the next generation.
Can somatic mutations occur in sex chromosomes?
No, they occur in the organism's body cells and cannot be inherited by the offspring .
Are mutations in somatic cells heritable?
Nothing in somatic cells is inheritable unless it shows up in the gametes as well. As such, if a somatic cell experiences a mutation, it can only affect that cell and any cell it creates.

What is the difference between somatic and gametic cells?
a germline mutation is one the was passed on to offspring because the egg or sperm cell was mutated. a somatic mutation is a mutation of the somatic cells (all cells except sex cells) that cannot be passed on to offspring.
People who have been exposed to excessive radiation often experience mutations If these mutations only occur in somatic body cells these people may?
experience an increased risk of cancer
How do mutations occur during mitosis?
reasorment of chromosomes can occur during meosis by crossing over
Can mutation heritable?
Mutations are able to be inherited if they occur in your mother or father's sex cells. This is known as a germline mutation.
Mutations that occur in germ-line cells are?
Somatic mutations occur in somatic body cells. These mutations are passed on to daughter cells during mitosis and to the offspring of those cells in turn, but are not passed on to sexually produced offspring.
Which kind of mutation has the greater potential to affect the evolution of a population a mutation to a body cell or a mutation in an egg cell?
Mutations that occur during gametogenesis (formation of egg and sperm) are called germ-line mutations. They are more significant than somatic mutations (which occur in body cells) because they can be transmitted to the next generation whereas somatic mutations are not transmitted to the next generation.
What happens if mutations occur in somatic cells of an organism?
A somatic mutation is one that occurs AFTER offspring have been conceived. This means that the mutations are not passed on to the f2 generation of offspring. An example we find in humans is cancer.
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
