Okay, so the question is, what best describes genetic mutations? so the first one is a disease caused by genetic mutations is always passed on to the offspring.
00:14
That is actually not true.
00:16
Because if it is a somatic mutation, meaning it occurs in one of the, not a germline cell, but one of the somatic cells, then that is not passed down to offspring.
00:30
The only genetic mutations are passed down to the offspring are those that occur in germline cells, typically your gametes.
00:38
And by that same logic, d is also out because somatic mutations cannot be inherited.
00:47
But it can be acquired during life.
00:51
Okay, so half that statement is true.
00:53
That leaves us to the other two statements, which is some inherited mutations can be good for the offspring.
01:04
And different genetic mutations cause a few forms of cancer.
01:07
Both of these are true.
01:10
Both of these are true, and that's what makes this question a little tricky, because the question is what best describes genetic mutations.
01:17
And so, while different genetic mutations can cause a few forms of cancer, it is not an instantaneous cause for cancer...
