Question

a. it is influenced by genes;
b. it is not influenced by the environment;
c. the variance of the trait in a population can be explained primarily by variance in genotypes;
d. A and C are correct;
e. A, B, and C are correct

Accepted Answer

Hello everyone. And in today's video, we have really short problems. So let's jump straight into it. That if a trade has low heritability, it means that sort of given certain scenarios that could come if a trade has low heritability. Now, I want you to recall from previous videos where heritability is and what it means for a trade. Heritability is a measure of trade variation in terms of what is affecting the variation in a trade. If a trade has a heritability of zero or close to zero, then it's mostly environmental factors as we see here, there are affecting the trade. However, if a trade has a heritability that is higher or is closer to one, then it is genetic differences that are affecting the variation in the trade. We see here that it is stated that the trade has very low heritability. So in in this scale of 0-1, it is closer to zero. And the trade will be mostly influenced by environmental factors. Looking at our answer choices, answer choice, a most represent this scenario where the environment is contributing to the variation of the trade. And so that will be the final answer to our question. I really hope this video helped you
