Black skin color is dominant to pink skin color in pigs....

Question

Black skin color is dominant to pink skin color in pigs. Two heterozygous black pigs are crossed.

What is the probability that the first and second offspring will have black skin?

Accepted Answer

Hi, everybody. Welcome back. Let's look at our next question. When Mendel crossed true breeding, yellow and green pea plants. What made him conclude that the green variant is the recessive treat? So Mendel had lines, true breeding lines, meaning lines of P plants that always produced yellow P S. Another line that always produced green peas when he crossed these. What were the observations he made that led him conclude that green was recessive. Let's put that up here. And he observed that in his first generation after the cross to his first hybrid generation or F one, all of the plants had yellow peas, despite the fact that the green pea parent had come from a line that always produced green peas. Then in his second generation, he had 25% of the offspring showing again that trait of green peas that trade reappearing with 75% being yellow. So that let him conclude this idea of dominant and recessive traits that green was a recessive trait being masked in that first generation of hybrids that inherited one trait from either parent. And it wasn't apparent again until the second generation, when offspring could inherit to the green traits from both parents. So let's look through our answer choices and see which one matches um those observations that led him to this conclusion. Choice A says he observed it in the green variant and a few peas in the F one progeny. Well, this is not correct. There were no greenpeace in the F one progeny. So choice A is not a correct answer. Choice B says it became the dominating trait in the F one progeny. This was definitely not correct. Um As there were no green peas in the F one progeny, um It definitely was not the dominating trait. So choice B is incorrect. Troisi says the trait was not observed both in F one and F two progeny while this also not correct because the trait did reappear in the F two progeny. So choice C is not correct. So here we're at choice D, it showed up only in the F two progeny and this is correct. There were no green peas in the F one progeny. See you in the next video.
