So we have our question, which is, which of the following traits are more likely to become widespread in the next generation.
00:08
So looking at how traits are passed on.
00:11
And our options, acquire traits that improve reproduction, acquired traits that improve survival, such as a long neck and drafts, inheritable traits that improve survival and reproduction, albino or albinism, which means there's no pigment in tree squirrels and wider black stripes in zebras.
00:28
So one thing we need to know is acquired traits, what they are.
00:33
Acquired traits are traits an organism gets during its life.
00:54
However, these traits cannot be passed on.
00:58
They are not heritable.
01:01
They are not able to pass acquired traits on to offspring.
01:05
Kind of a major example we can think about is like if you lose your hand, you have to amputate your hand, somehow like, let's say an animal eats your hand.
01:13
If you have children, your children are not going to be born with a missing hand just because you lost your hand during your life...
