Not answer this question i talk about ingeridans, it says, the dominant are a little produces great -colored fruit in tomatoes, while the aggressive one produces yellow fruit.
00:08
So when you have the homoseagus dominant or the heterocylus, you're going to get get, and when you have the homoseilocylusium down, get yellow.
00:16
You also have the pea being.
00:19
When you have the homozygous dominole or the heterocylus, you're going to get a purplish colored stem in tomatoes, while the aggressive, the homosephoidisive is if you're going to cut for, a green color stems.
00:37
So it says, predict your phenotypic ratio when the p1 genotypes are heterozygose, are heterocygous, are heterocygous with a double homocellic excessive.
00:51
In order to get the gametes, you have to mix each of these analyses with each of these p -a -lil, and the combinations are going to be your limits.
00:57
In this case, the gametes are going to be this, this, this, and this.
01:04
Okay and the only possible gamut from this parent is going to be this one okay so you have to complete your pattern square and you're going to get heterozygos heterozygos heterozygos heterocygote recessive homoceive recessive heterocyghyg and a double homocygose recessive they're asking you for your phenotypic ratio so here this is going to be great and this is also great but this is great and green stems so you have 1 for great and purple stems and one for great and green stem.
01:45
Now this is yellow tomatoes with parpleash stems and this is yellow tomatoes with green stems.
01:52
And this is yellow tomatoes with green stems.
01:57
So you have one, one, one and one for your phenotypic grade.
02:03
This is a phenotype equation.
02:03
This is the answer to question too.
02:06
The next question says, what is the probability in percent of two parents with type a blood, heterocygot, having a child with type a blood? remember that, well, in this case, it says that both parents have a heterocylus for type a.
02:21
It means they are like this, because the o allele is recessive, remember.
02:26
So this is your cross.
02:26
Let's make up an n -square.
02:33
It's not homo -segygo -domeinot -heterocytocles, heterotegot, they are asking you, the probability in percent of these two parents having a child with type a blad.
02:43
So you have a total of four possibilities.
02:46
In order of those four possibilities, one, two, and three are going to be, i'm going to have type a blood.
02:52
So in this case, you have to divide three by four and it is equal to 0 .75.
03:00
If you want this in percentage, you have to multiply by 100 and you're going to get 75%.
03:06
So 75 % is the answer for this question.
03:11
The next question says, the intensity of pigments in the color of mice is under the control of napper of alils as shown below.
03:19
You have d1, d2, and d3...
