In order to answer this question, i talk about inheritance.
00:03
You have the following cross.
00:05
Heterocytes for g, heterosig for r, and heterosigel for t with heterosig for g, heterosig for r, heterocig.
00:14
And they are asking you to get the homocycles dominant for g, and the homocycles dominant for t.
00:22
Now, in this case, we can make three monohrabri -pan square squares.
00:25
Heterosig with heterosig, r with hittor -sigigr with hittor -siggo -r, with heterosigero -sig.
00:30
And we want to have the following.
00:33
Hitrocygos, and hitrocygos, you get homocygloid nominal, hitrocygos, and homozygos decisive.
00:42
That same for r.
00:46
Mosaigos, dominole, heterozygos, hitrocygos and homozygos recessive.
00:51
And finally the heterocygoyles t, you get homozygos dominant, hitrocygos, hitrocygos, and homozygot decisive.
01:00
So, what are the chances of getting this? genotype here.
01:04
For homozygos dominant, you have, one out of four possibilities.
01:07
So you have one quarter for the homozygoyal dominant.
01:10
G.
01:10
For the heterocygots are you have one and two out of four.
01:14
It means two quarters and two quarters is the same as one half.
01:17
And for the homozygous dominant t, you have one out of four.
01:20
It means one quarter.
01:22
So you have to multiply all of this and you're going to get one three three.
01:26
This is the answer for this question.
01:29
The next one says if you were to calculate the odds of getting two homozygotes in one hetero cygote, would your answer be different? and if different, what would be the value? so in this case, you want two homocygos, homo, homo, and hetero, like this.
01:50
Okay? so, for example, let's suppose that you want the homocygles for g, the homocygous and the heterocygous and the heterocygous for t...
