Which individuals in the pedigree are identified and labeled carriers for red-green color blindness?

Answers

Do you have the pedigree to share? Red green color blindness is an x linked trait, which means that it is found on the X chromosome. X linked traits are often recessive, and this is why they usually show up in males, such as the case of red green colorblindness. A male has only one copy of the X chromosome, so if a recessive x linked trait is present, he does not have the option of the dominant version of the trait to show up. A recessive X linked trait can present itself in a female, but since she has two X chromosomes, she would need to have two copies of the recessive trait for it to present itself. This is why color blindness is less common, but still possible in females. I hope this helps you with your pedigree.
