So in this question, we're looking at sex determination in humans androsophila are similar, and we're given a multiple choice.
00:09
Well, in humans androsophila, an x, x is female, and an x, y is male, right? so we have two options here that both follow that.
00:22
If we look at b, where it says males and both have one y chromosome, and females do not have.
00:42
Have a y will not have a y.
00:50
That's true.
00:52
And then when we look at d, males have one x chromosome and females have two x chromosomes.
01:14
Both of these look very, very true.
01:18
But when you start getting into, when you start getting into x exceptions, right, you can have an x, x, y and you are male.
01:29
You can have an x, x, x, and you're a female.
01:33
We start looking at exceptions.
01:36
We care more not about the y than the x...
