Question

select all that apply
which describe red-green colorblindness?
□ sex-linked trait
□ very rare in females
□ dominant trait
□ located on autosomes

Explanation:

Red-green colorblindness is an X-linked recessive trait, meaning it is carried on the X sex chromosome. Since females have two X chromosomes, they would need two copies of the defective gene to express the trait, making it very rare in females. Males, with only one X chromosome, express the trait if they inherit the defective X. It is not dominant and is not located on autosomes (non-sex chromosomes).

Answer:

• sex-linked trait
• very rare in females
