Accepted Answer

Everyone. Let's take a look at this question together. Which of the following is not an example of a continuous trait. Is it answer choice? A human height, answer choice. B human foot size, answer choice, C human blood type or answer choice. D human skin color. Let's work this problem out together to try to figure out which of the following answer choices is not an example of a continuous trait. So in order to solve this question, to figure out which of the following is not a continuous trait, we have to recall what a continuous trait is so that we can eliminate them from the answer choices to figure out what the correct answer is. And we know that continuous traits are traits that have an infinite number of possibilities, meaning that they are controlled by the cumulative actions of many genes and the environment. And so traits that are not continuous are discontinuous traits which are traits that are controlled by a small number of genes. And an example of a discontinuous trait is tongue rolling. Whereas an example of a continuous trait is height or weight. And so looking at our answer choices, which of the following are continuous traits. Well, we know that we said that human height is an example of a continuous trait. So we know the answer cannot be answer choice A and we also know that human foot size has an infinite number of possibilities. So answer choice B is also a continuous trait and not the correct answer. And we know that human blood type is a qualitative trait, meaning that human blood type is a discontinuous trait. So answer choice C is not an example of a continuous trait making answer choice. C human blood type, the correct answer. And we also know that human skin color is an example of a continuous trait and not the correct answer because skin color has an infinite number of possibilities similar to height and foot size. So answer choice C human blood type is the only answer choice here. That is not an example of a continuous trait because we know that continuous traits are traits that have an infinite number of poss disabilities because they are controlled by the cumulative actions of many genes and the environment. Whereas traits that are not continuous are discontinuous traits which are controlled by a small number of genes. And an example of a discontinuous trait is human blood type, which is answer choice. C, the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
