Question

Horses can be cremello (a light cream color), chestnut (a brownish color), or palomino (a golden color with white in the horse's tail and mane). Of these phenotypes, only palominos never breed true.

Predict the F₁ and F₂ results of many initial matings between cremello and chestnut horses.

Accepted Answer

Hey everyone. Let's take a look at this question together. What is the phenotype IQ ratio of the offspring? When two mirabilis jalapa plants with pink colored flowers are crossed. So we know that these plants show in complete dominance. Because we have those pink colored flowers, which we know that when we have incomplete dominance and we see a pink flower, we know that the home is august dominant, gives us that red color. The hetero ziggy's gives us the pink and the recessive homesickness gives us white. Because that heterosexuals that gives us pink has won a little for red and one for white. And because of incomplete dominance, that dominant allele does not entirely mask that recessive allele, thus giving us the pink colored flower. So in the case of having to plants with the pink flowers, that means that we are crossing to hetero zegas plants and so their offspring look like this. And so we end up with that 1 to 1 ratio. Where we have one plant that is red, we have two that are pink and we have one that are white, which means that answer choice. C. Is the correct answer. Because when we cross to plants that show incomplete dominance and have those pink colored flowers, we end up with a 1 to 1 fanatic ratio or answer choice C. The correct answer. I hope you found this video to be helpful. Thank you and goodbye
