So today we're going to be going over number six in chapter two, the biology of behavior.
00:08
And essentially this question is asking about our knowledge of adoption studies.
00:17
So i'm going to draw a little bit of a mock family here to kind of demonstrate this a bit better.
00:24
So let's say these two are the parents.
00:29
And then we'll say these guys down here are the siblings.
00:36
And i'm actually going to draw one sibling in pink.
00:40
To represent the adopted sibling.
00:47
So down here are the children.
00:53
So when scientists use adoption studies, they're essentially trying to investigate if the adopted sibling is more similar to their biological parent or to their adopted parent.
01:05
So i'm actually going to draw the biological parent of the adopted sibling here.
01:21
So if scientists find that the adopted sibling is more similar to their biological parent on a certain parameter, then it is more likely that that parameter is more heavily influenced by genetics.
01:37
And this is the case because the adopted sibling shares genetics with their biological parent.
01:45
So i'll write that down here...
