Quizplus · Accepted Answer

The Punnett square shows the inheritance of red-green color blindness, which is a sex-linked recessive trait. This means that the gene for color blindness is located on the X chromosome and that males, who only have one X chromosome, are more likely to express the trait than females, who have two X chromosomes. This type of inheritance is referred to as sex-linked inheritance.
