The genes for red and green color vision are located on the X chromosome. Men inherit XY chromosomes, and women inherit XX chromosomes. Red-green colorblindness is the most common colorblindness in humans, far more common than blue colorblindness. Red-green colorblindness is caused by a recessive gene and disproportionately affects one gender more than another. Which gender do you think is more affected by inheriting a mutated gene that causes red-green colorblindness? Why do you think the recessive gene contributes to this effect?

Choose one animal (cheetas) and research on the internet what has contributed to this animal becoming "endangered" or "threatened." what animal you have chosen? how long has the animal been endangered or threatened? what has contributed to this animal’s endangered or threatened status? why is it important to save this animal from extinction? after researching and gathering facts, write a 350-word letter from the point of view of an animal rights' activist. be sure to include at least five facts that you learned from your research.
