Hello all, so here in this question, the mendelian genetics, it's about the mendelian cross and it says that there is some cross given and first question is that what are the two traits here? so here the traits that involve is the shape of the seed, shape of seed, then color of seed, color of seed.
00:35
So here the traits that given here, shape is round and wrinkled and here the color is green yellow.
00:55
So and the next thing for each trait, what are the two phenotypes? so the two phenotypes that here, we already told that round and wrinkled, green and yellow.
01:08
The next one is that which phenotype is dominant and recessive? here for color, the dominant phenotype is green, it is yellow.
01:22
For color, it is yellow, dominant one is yellow and for shape, the dominant one, it is round.
01:42
So here then the next thing we can say, the phenotypic ratio of f2 gyration and the p1 square.
01:53
So here the f1 and f2 p1 we need to make.
01:56
For that, first we need to take the gametes.
02:00
So in this question, the gametes are the parenteral gyration is round yellow with wrinkled green.
02:08
So here it is round yellow wrinkled green.
02:21
So here the parent that we will get from the f1 gyration first, here it is the parent and this crosses we will get, first one it is we can write it as r y crosses with r y.
02:47
So it will be, there will be r r y y.
02:54
So this will be the gamete we will get.
02:56
So by drawing a punic square, so take this is the punic square and for this punic square, we will have here the gametes.
03:05
Gametes we will write here, here it is r r y y.
03:18
It will be r y, it will be r y, it is r y and small r small y.
03:27
Here same, we can write it as here is capital r capital y.
03:34
Capital r small y, small r capital y, small r small y...
