Hello everyone.
00:02
So today the question that is given to us is about the genetics.
00:06
It is basically about the two characteristic species of the horses.
00:10
The one is a chestnut and the second one is the bull.
00:13
We need to talk about them.
00:14
But here the question over question is about the mendel's law of genetics, which further investigated by the scientist in order to understand whether it is applied to the other species as well, because mendel studied the peoples.
00:29
So what happened is that there is.
00:30
Are people, these people in the england, there are biologists in the england who try to study this mendel's law in the race horses.
00:38
So what they do is they basically cross certain breed of bars and they observe the three conditions that is a chestnut stallion when mated with chestnut mares, they always produce chestnut folds.
00:52
This sign here is representing the mating, remember.
00:56
And when we talk about the stallion, remember we are talking about the male horses, mares female horses and foals are the young horses.
01:04
So that is the first observation.
01:06
The second is that when some black stallion is mated with chestnut mares, they only produce black foals.
01:15
And the last condition, your last observation is that some black stallion, again, when mated with chestnut mares, what they produce is the mix of black foals and chestnut falls.
01:26
Now we need to understand which color is dominant here.
01:30
Chestnut, which is, which is, is basically a red color or the black color.
01:35
So here for that, we can hypothesize the two things.
01:40
First, whether the chestnut is dominant and the second thing is whether the black is dominant.
01:49
So let's say for chestnut here, remember the chestnut is a trade that present on this characteristic e -locust.
01:58
And because we need to find out here whether it is a recessive trait or a dominant trade.
02:05
So let's talk about the, we can say, cross here.
02:10
So for the first cross, let's talk about the first where a chestnut stallion is mated with chestnut mares.
02:16
And let's take the capital c and the small c as an alley.
02:20
So here, let's give a chestnut stallion, let's say a small c.
02:28
So, this will be small c and small c.
02:31
And again, the chestnut mares will eventually be small c and small c because both are chestness.
02:36
And if we form the pannet square here, so this will be your pannett square, c and c here, and c here.
02:44
And if you cross them, if you cross them or if they made, they basically produce the same kind of genes eventually because they are same and that is small c, small c, c and small c, c, small c, c.
02:57
Again small c small c and small c small c so all the progenies are chestnut eventually because all of them have this characteristic allele that is small c small c for that we can say okay that is true here that they all produce the chestnut so first condition is proven here let's talk about the second condition which is specific because now here we have a black stallion so let's say we give this black stallion a capital c and it is made to make with the chestnut mirror...
