00:01 Looking at a situation that is perfect for a punnance square.

00:05 So snap dragons don't have color dominance, which means that, you know, if they have one gene of red and one gene of white, then they end up having pink flowers.

00:18 So we're thinking about crossing two different types of snap dragons.

00:21 So let's draw a punant square.

00:23 It also looks like an area model depending on what you've used in the past.

00:27 And we'll look at our snapdragons.

00:32 So the first one is a pure red snapdragon.

00:38 It's going to call it sd.

00:40 And then the other one is a pure white snapd.

00:47 And that means that for their genes, the pure red snapdragon has a red gene and another red gene.

00:56 And then the pure white one, i apologize, i don't have a white color here.

01:03 Has a white gene and a white gene.

01:05 So when we combine these, we want to figure out, well, what's the probability of getting a red offspring, of getting a white offspring, getting a pink offspring, et cetera.

01:18 So let's see.

01:22 When you combine these, in each of these cases, one of these genes comes through from each of the two snapdragons.

01:34 Trying to find is they're all the same...

Question

Mendel found that snapdragons have no color dominance; a snapdragon with one red gene and one white gene will have pink flowers. (a) If a pure red snapdragon is crossed with a pure white one, complete the following Punnett square.
