You know that to answer this question we talk about inheritance.
00:02
It says a pole, the poled or hornless condition is dominant over the horned condition.
00:07
So when you have a homocylus dominant or the heterocylus, you're going to get hornless, and when you get a homozygoous as if you're going to get horned, the horn condition.
00:21
So it says a certain poult bull is bred to three cows.
00:26
So you have a bolt that is hornless.
00:29
Okay, so you have that this is the male.
00:32
This is the bull.
00:32
This is the general for the bull that can be.
00:34
Either homozygoyles dominant on heterocygous and it is bred with three cows predict the genotypes for each of the following so you have your poult let's go for question a okay your bold a bowl with a horned cow so a horn cow so a horn cow is like this homozygum excessive and it says that they are producing a polled calf it means like this this is bold remember in this case remember that i'm off -pring here is one a little from his parents so in this case, these pole cals can be either like this, homocygous dominant or heterocygous, right? so let's suppose that this is homozygous dominant.
01:21
Can this be homozygous dominant? and the answer is not because this parent here can only transmit grecipaliol to the off -print.
01:29
So it means that this all the off -pring must have at least one basis -p that is coming from this cow here.
01:37
And what about this parent here? well, this dominant p should come from the bull.
01:41
And the bull can be homozygous dominant or heterocygos, because in this case, if you have the homocygous dominant, then this bull can transmit either this or this, and you're going to get this, right? and also the bull can be heterocygose, and in this case, if the bull transmits this dominant p, you're going to have pulled, pulse, calls, and if this bull transmits the recessive p, you're going to get homocycolysis.
02:07
So in this case, actually both the homocybos dominant and the heterocygios are possibilities for this cross.
02:16
Okay, so you can have here either the homocylus dominant or the heterocygoyles.
02:21
In this case, remember that they are only giving us the information of one of that cloud.
02:28
So we cannot, only with the information we cannot know exactly which genotype is for the bull.
02:34
If they would tell us that from this cross you only get that you only get that you can not, you only get pulled off -pring, then in that case, you would get the homocylus dominant.
02:43
But in this case, they are only showing us one of the off -pring...
