mutations in the reproductive cells of the body can be carried on to the next generation but mutations in the body cells won't alter the genes.
Reproductive cells are capable of undergoing meiosis to form gametes
Some mutaions of DNA in body cells affect genes that control cell division. This can result in the cells growing and dividing rapidly, producing cancer. If this is not right I'm sorry. I'm a little rusty on biology.
Incorrect.
yes, true.
Cancer
The testes, or testicals, produce sperm cells.
No. As long as the mutation does not occur in the reproductive cells (sperms or ovum), it will not be pass on to the offspring.
This is because body cells do not contribute genetic material to sex cells.
They happen after the organism has been born, and often lead to tumours and cancer (caused by carcinogens). Other types of mutations can be caused by mutagens, which mutate the DNA of a cell. It doesn't affect the DNA of every cell in the organism/ reproductive cells, so isn't passed on to offspring
In male pigs, wastes and reproductive cells are transported outside the body through the penis.
Body cells do not undergo meiosis. Reproductive cells undergo meiosis, body cells, mitosis.

Mutations in sex cells can be passed on to children. Mutations in sex cells only affect offspring. Mutations in sex cells do not affect the organism.

yes, true.
Cancer
All your cells except for red blood cells and your reproductive (egg & sperm) cells.
