Accepted Answer

Hi, everyone. Let's look at our next question. It says which of the following sentences regarding di hybrid cross is false. So let's think from our content video, what a di hybrid cross is. And that's when we look at the offspring of a cross of parents where we're looking at two different traits. So something like coat color and eye color, coat color and coat texture. So we're looking at how those offspring inherit combinations of those two different traits from the two parents. So with that in mind, let's look at our answer choices. Let's note the choice D is none of the above. So there exists the possibility that none of these statements is false since we are looking for a false statement to keep that in mind. So let's look at choice. A choice. A says a di hybrid cross is a type of genetic cross that involves two different traits. Well, this is true and therefore, it's not our answer. Since we're looking for a false answer. Choice B says A di hybrid cross involves two parents. This is also true and therefore not our answer. Then choice C says in a die hybrid cross the offspring will have eight possible combinations of the two traits. Well, let's think about this and how many different combinations you have. So, if you've got two different traits, you've got two parents. So here we've got parent, one and parent too and we know that parent one, we're looking at two different traits and we'll call these traits, one and two Parent to, we're also looking at two traits And we'll just call the trait the parents shows as three and 4. So let's think about the possible combinations of these traits that the offspring could inherit. Well, the offspring could inherit trait one from parent, one and trait three from parent to, since they inherit one from each parent, they could inherit trait one from parent, one and trait four from parent to Or they can inherit trait to from parent, one with trade three, from parent to or trade to from parent, one with trade four from parent to. So that gives us four possible combinations Of the two traits. So therefore, choice C which as they could have eight possible combinations must be false. And since we are looking for a false answer, then choice C is going to be our correct answer. Choice here and we can go ahead and cross out choice dean under the above since we did get a correct false statement. So again, which of the following state sentences regarding di hybrid crosses is false. Choice si and the di hybrid cross, the offspring will have eight possible combinations of the two traits. See you in the next video.
