Q: Red-green colorblindness is an example of what kind of trait?


Read this paragraph and choose the correct option from the provided answers:

One example of a sex-linked trait is red-green colorblindness. People with this type of colorblindness cannot tell the difference between red and green. They often see these colors as shades of brown ( Figure below ). Boys are much more likely to be colorblind than girls ( Table below ). This is because colorblindness is a sex-linked, recessive trait.

 Choices:

- dominant

- fatal

- adaptive

- sex-linked


A:
sex-linked
