Gametes are single cells, either egg or sperm, with unmatched DNA that join to form a single cell, a zygote with complete DNA, which grows into a new individual. A cancer cell could not 'affect' a gamete. Cancer is an uncontrolled growth of cells that do not function properly. This is usually the result of damaged DNA. If a gamete had defective DNA, it would create a zygote with defective DNA that would grow improperly, like a cancer. Such zygotes would not develop properly, and would either not attach to the womb, or would spontaneously abort early in pregnancy.
Offspring usually contain an infinitesimally small number of cells from the mother. Likewise, the mother contains some infinitesimally small number of her offspring's cells. The frequency of such cells compared to the rest of the cells of the body are so rare that they do not normally affect the health of either the mother or the offspring. It might be theoretically possible for a cancerous cell from the mother to get into the offspring long after the gamete. As far as I know, this has never been proven to have happened.
Some viruses can cross the from the uterus (part of the mother) to the placenta (part of the baby). This is why some viruses (for example rubella) can cause birth defects. Most bacteria cannot cross, and even some rather sinister viruses, like HIV, don't always cross. Some women who are HIV positive have babies who are HIV negative.
The separation of the mother's circulatory system from the baby's circulatory system is one of the wonderful advantages of placental animals that allows diseased mothers to give birth to disease-free offspring. This gives mammals a survival advantage over other types of animals. For example, diseases pass more easily from a bird to its eggs.
What else can I help you with?
Who does somatic mutation affect?
A somatic mutation is one that occurs in any body cell with the exception of the gametes (sperm and eggs). A somatic mutation cannot be passed on to offspring, so it affects only the person with the mutation.
True False All mutations can be passed on from a parent to an offspring?
Only mutations which occur in the gametes. Mutations in somatic cells ( body) are not passed on to offspring. Example: A mutation in skin cells leads to skin cancer, but this cannot be passed on to offspring.
What is a mutation that affects the gametes of an organism?
A point mutation is a mutation that can affect the gametes of an organism. This type of mutation involves a change in a single nucleotide in the DNA sequence, which can result in altered genetic information being passed on to offspring.
As a result of sexual reproduction an organism can pass a gene mutation to its offspring if the mutation occurs in?
the gametes of the organism. Gametes, such as sperm and egg cells, contribute genetic material to the offspring during fertilization. Mutations that occur in gametes have the potential to be passed on to the next generation.
How does a mutation in a sex differ from a from a mutation in a non-sex cell?
A mutation in a sex cell, such as a sperm or egg cell, can be passed on to offspring and affect future generations. In contrast, a mutation in a non-sex cell will only affect the individual and is not passed on to offspring.
Mutation that occurs in gametes and can be passed to the offspring are what?
Germline mutations are changes that occur in the DNA of an organism's gametes (sperm or egg cells) and can be passed on to their offspring. These mutations are present in every cell of the resulting offspring's body.
Why only mutations in gametes can be passed on to future generations?
Mutations in gametes can be passed on to future generations because gametes are involved in reproduction and carry genetic information that can be inherited by offspring. Somatic mutations, which occur in non-reproductive cells, do not affect the germline and therefore cannot be passed on to future generations.
Where must a mutation occur if it passed to offspring?
In the gametes (e.g. sperm or egg)
Would a skin cell mutation on your hand affect your offspring?
No, a mutation in a skin cell on your hand would not affect your offspring because mutations in somatic cells (like skin cells) are not passed on to the next generation. Offspring inherit genetic information from germ cells (sperm and egg cells) which are not affected by mutations in somatic cells.
How are similarities passed from parent to offspring?
Through the parental genes forming the two gametes.
True False All mutations can be passed on from a parent to an offspring?
Only mutations which occur in the gametes. Mutations in somatic cells ( body) are not passed on to offspring. Example: A mutation in skin cells leads to skin cancer, but this cannot be passed on to offspring.

Can mutations be passed from parents to offspring?
Yes, mutations can be passed from parents to offspring. Mutations are changes in the DNA sequence that can be inherited if they occur in the germ cells (sperm or egg cells) of the parent and are passed on to the next generation.
What is most likely to alter the DNA in an individual's gametes before it is passed to an offspring?
Exposure to mutagens such as radiation, certain chemicals, or errors in DNA replication during cell division are most likely to alter the DNA in an individual's gametes before it is passed to an offspring. These alterations can lead to mutations that may be inherited by the offspring.
As a result of sexual reproduction an organism can pass a gene mutation to its offspring if the mutation occurs in?
the gametes of the organism. Gametes, such as sperm and egg cells, contribute genetic material to the offspring during fertilization. Mutations that occur in gametes have the potential to be passed on to the next generation.
How is genetic information is passed from parents to offspring?
The traits are passed on through gametes, in which the males sperm carries, and the females eggs are carried. Each only contains one of each chromotids which decides your traits depending on the matches the chromosomes make.
