What is the relationship between genotype and phenotype?

Question

Accepted Answer

Welcome back. Here's our next problem blank. Are the observable physical traits that are the outcome of the expression of the blank of an individual. Now again, we always recommend looking over the answer choices. Um And I'm going to say in this case if you're on a test you're trying to get through as quickly as possible. You have a quick um hint given to you by your answers. Can we look at our answer choices, choices A. C. And D. All have Jenna types as the first answer. Choice B. Has a different answer. It says phenotype sis. So without even thinking about the problem or remembering which is which I've only got one that's different. And since it's multiple choice, that's going to point me to that choice B. As the correct answer. So that's just a little test taking tip. But let's look at the problem itself because you might not have it turn out like this obviously on a test. So the observable physical traits that are the expression of blank. So observable physical traits we can recall from our content videos are the phenotype sis. So that's what we see on the outside of the individual. Um And that is the outcome of the expression of and that would be the genes. So the individual has genes for certain traits and how they get expressed the appearance of the individual. The anatomy. The individual are the phenotype sis. So for instance you could have a gene for a recessive trait. So you have the gene for say you're a woman with a gene for um color blindness. But if you only have one copy of this gene and you have a second copy for normal vision, your phenotype will be having normal vision. Um That can go unexpressed because it's masked or perhaps the expression of that phenotype is affected by palla genic inheritance. You've got genes that work together. So we're looking at Choice B phenotype sis and jeans. Vienna types are the observable physical traits that the outcome of the expression of the genes of an individual. So Choice A. Isn't correct because that has Jenna types as the first choice choice C also has Jenna types and then uses phenotype as the expression of the as the second choice. So obviously phenotype is not what's expressed. Choice D not correct. It has genotype is the first choice. Even though it also has genes as a second choice. It is important to note while we're thinking about this topic that phenotype can also be affected by the environment. So for instance, someone might have inherited genes to be very tall. But if they're malnourished they might their phenotype they might end up being a short person. So phenotype is not just affected by genes that can also be affected by the environment. So just a little extra note there. See you in the next video
