00:01
In order to answer this question, we talk about inheritance.
00:03
This is infallel genotype homocyglysis for both genes.
00:08
Gives single comp.
00:11
Single comp.
00:13
Then it says that when you have the fumasibus allel r, also the dominant all right and the dominant alll p, you get well not come.
00:26
Then when you have either this or what i say it here.
00:35
Like this, you're going to get rose comb.
00:41
Okay, so this is what you have here.
00:43
The phenotypes in the phenotype that you're going to get.
00:45
If a single combined birds are crossed with birds of a true breeding, walnut combined strain, it means you're going to create a single combined birds.
00:54
It means like this, with a true breeding, walnut combined, it means like this.
01:03
It predict the proportions of comp, a types that will appear in the f1 and if two.
01:07
So what is the only possible commit produced from this offering? it is going to be like this.
01:13
And the only commit produced by this, by this parent is going to be like this.
01:20
So you are going to cross them, you're going to get that this is going to be the genotype for all the f1.
01:25
This is the only genotype possible for the f1, right? and this is going to be according to this while not comp.
01:32
So all the f1 is going to stop this phenotype here.
01:35
Now in order to get the f2, you have to cross this.
01:41
With this.
01:42
So in order to do this cross, you have to make a dihavi panel square.
01:47
So you have, you want to get the gametes first from both of them.
01:50
Both are going to have the same gametes because both have the same genotype.
01:53
So you have to mix each of these are alines with each of these p -alil.
01:57
So you're going to get the following gametes that are this, this, this and this.
02:05
So you are going to set a panel in this square that is going to be like this and this.
02:20
And here i'm going to have this.
02:30
Now you have to complete all of these.
02:33
Let me complete this.
02:34
Okay, so this is going to be your panel in square.
02:36
This is going to be the f2.
02:37
All of this is going to be the f2.
02:41
And they are asking you for the proportions of comp types that will appear in the f1 and f2.
02:47
So practically they are asking you for the proportions of phenotypes.
02:49
Here in the f1, the proportion is going to be 1.
02:54
1 ,000, practically.
02:55
Okay.
02:56
It means 100 % are going to be.
02:59
I want to have walnut pumps.
03:02
But this is going to be different here, as you can see, because you have many other, many possibilities here.
03:07
So let's first look for this phenotype here.
03:11
That is this one here, okay? that walnut cup.
03:17
So according to that, this is going to be one not camp.
03:20
One, two, three, four, five, six, seven, eight, nine.
03:30
And that is you have nine that are going to be one that comp.
03:35
As a total number of possibilities, he is 16, you're going to have this proportion.
03:40
Okay, 9, 16.
03:42
Now let's look for single comp that is homozyrocessive for both genes.
03:48
And you're going to have here only one that is going to be this.
03:52
So you have 1, 16 that is going to be, they're going to have single com.
03:58
And practically all the remaining are homozygo recessive for one allele and dominant for the second allele are going to be, i'm going to have gross comp.
04:11
So all the remaining that you have here, you have one, two, three, four, five, and six, all of them are going to code for gross com.
04:23
So you have that six divided back 16 is going to be, going to have a rose com.
04:28
So these are the proportions of phenotype for the f2.
04:31
This is the proportion for phenotype for the f2.
04:34
Then, the next question says, what is a probable genotypes of binds, like fowls, and a walnut, a ghost, and a wild not with a ghost mating that would produce organes in this proportion.
04:46
We have the following proportion that is 3, 3, 1, 1.
04:52
Okay, so we have a walnut with a ghost.
04:58
The genotype for walnut is like this...
