Question

PLEASE HELP///3. Heather had a color blindness test, and she was surprised to discover she suffered from red-green colorblindness. She told her biology teacher, who said, “Your father is color-blind too, right?” How did her teacher know this? Why did her teacher not say the same thing to the color-blind males in the class?

Answer 1

Answer:

In order for a woman to have the colorblind trait, they need to be X^cX^c, meaning that they have to get the trait from both their parents. Males can either have X^cY or X^CY and since Heather has it, it is definitive that her father had X^cY, which means that he is colorblind. Males in her class, on the other hand, can get it from either their mother or father.

Explanation:

Hope this makes sense!!
