1 00:00:00,330 --> 00:00:02,009 So the answer to this question is that both the 2 00:00:02,009 --> 00:00:06,730 skin color and the disposition appear to be related in these 3 00:00:06,730 --> 00:00:10,370 families, as opposed to height, doesn't appear to related in 4 00:00:10,370 --> 00:00:14,220 our first family. Now what do we mean by this? All 5 00:00:14,220 --> 00:00:15,800 I mean is that when we look at the son 6 00:00:15,800 --> 00:00:19,650 here in the first example, he's much taller than the parents. 7 00:00:19,650 --> 00:00:22,950 Both the parents are short, so we're asking the question, 8 00:00:22,950 --> 00:00:25,390 where did the trait of the son being tall come from. 9 00:00:25,390 --> 00:00:27,330 Not only does it not appear to come from either one 10 00:00:27,330 --> 00:00:29,080 of the parents individually, but it doesn't look to be a 11 00:00:29,080 --> 00:00:32,549 combination of the pair's height either. In the case of skin 12 00:00:32,549 --> 00:00:35,770 color and disposition though, we see that both the daughter and the 13 00:00:35,770 --> 00:00:39,410 baby share the same skin tone as the parents so it 14 00:00:39,410 --> 00:00:43,230 appears as if that trait was related in this case. And 15 00:00:43,230 --> 00:00:46,750 the same thing for disposition. While one parent seems to be 16 00:00:46,750 --> 00:00:50,680 sad most or all of the time, the children are happy and 17 00:00:50,680 --> 00:00:53,700 resemble what the other parent looks like most of the time, 18 00:00:53,700 --> 00:00:57,480 which is having a happy or really cheery disposition. Now it's 19 00:00:57,480 --> 00:00:59,780 really important to remember as we go through this lesson and 20 00:00:59,780 --> 00:01:02,550 all the lessons in this course Just because a trait appears 21 00:01:02,550 --> 00:01:06,530 to be related or to be inherited in a particular ways. 22 00:01:06,530 --> 00:01:09,940 Looks can be deceiving sometimes. And we will talk in great 23 00:01:09,940 --> 00:01:14,030 detail about what aspects of traits have a genetic component and 24 00:01:14,030 --> 00:01:17,030 which of those might have an environmental component down the line.
