So this question is asking us which term from the key represents when a single gene produces a variety of phenotype.
00:13
So we have one gene, and it's affecting multiple outputs.
00:21
So this is actually a definition of a pliotropic gene, which is when a gene affects seemingly unrelated traits.
00:31
So in your book, it gives you the example of marfan syndrome, which is a disease where a mutation in a single gene results in disproportionately long arms and legs, poor eyesight, a weakened aorta.
01:03
So there's all these traits that derive from a single mutation in the marfan syndrome gene.
01:17
So this is actually the definition of c, a pliotropic gene, because one gene is regulating multiple traits.

This isn't, you know, the counter example is what we see with mendel's p's...
