Okay, guys, so this question is asking us about vestigial wings.
00:04
And vestigial wings are really interesting because they are basically for show.
00:08
An organism has these wings and they cannot fly, but they have the wings there.
00:14
So if we're in biology, we're thinking of flies when it comes to residual wings.
00:20
Whereas if you could just think about any other organism, you could think of an ostrich.
00:24
They also have wings that they cannot use for flight.
00:27
In order to understand this question, i kind of want to work backwards.
00:30
Instead of telling you the answer and why that answer is right, i want to tell you and have you understand why the other answers are wrong.
00:38
So we want to understand the difference between dominant and recessive.
00:41
So if you were to do a punnet square, these uppercase r is right here, right here and right here, stand for normal wings, meaning the wings that an animal has that they can actually use to fly.
00:56
And this little r is going to stand for wings that, they can't use to fly or the sigill wings...
