So your first question is about whether the characteristics that are listed like hair color, eye color, facial features are either genotypes or phenotypes.
00:10
And those would be phenotypes.
00:11
They're the way they look.
00:15
They are observable traits.
00:18
Then secondly, you ask, which of the characteristics are the result of homozygous genotypes and which are from heterozygous? well, not knowing we need to know what is dominant and what is recessive.
00:37
So for instance, you have that their hair color was, i believe it is brown.
00:44
They both have brown hair, and so they could either be brown is usually dominant over blonde, so it could be either a homozygous or it could be a heterozygous in that case.
00:58
And again, with the other, with the eye color of hazel, probably, again, that's not necessarily dominant recessive, brown and blue we have kind of in between.
01:10
So that we would need to know more about those traits in order to give specifics.
01:18
Now, it says on number three, which characteristics in the above description are from a single gene inheritance.
01:28
And a single gene versus a polygene involves traits that come from one gene, which the polygenetic inheritance means involves traits that are controlled by two or more genes...
