PROBLEM
• Is the occurrence of Color Blindness in my family the same as the
general population?
RESEARCH
• Summarize your research here in three to five significant facts:
– Tritanopia: People affected by Tritanopia are dichromats. This means the S-cones are completely missing and only long- and
medium-wavelength cones are present.
– Deuteranopia: The medium wavelength sensitive cones (green) are missing at all. A Deuteranope can only
distinguish 2 to 3 different hues, whereas somebody with normal vision sees 7 different hues.
– Protanopia: Color-blindness resulting from insensitivity to red light, causing confusion of greens, reds, and
yellows. It is hereditary and is the most common form of color-blindness.
– Tritanomaly, Dueteranomaly, and Protanomaly are mixes of their original form and normal vision, and they are
more common.
– Protanopia’s Male percentage: 1.01% Female: 0.02%, Dueteranopia’s Male percentage: 1% Female .1%, and
Tritanopia is very rare, 1 out of 10,000 people have it. Protanopia is Red-Green Color Blindness, Deuteranopia
is basically Green Color Blindness, and Tritanopia is called Blue- Yellow Color Blindness, but they can actually
see Blue already.

HYPOTHESIS
• If 9.5 out of every 100 people are Color Blind, Then about 1 or 2
people out of 15 are Color Blind in my family, Because that would
match the percentage of occurrence.
PROCEDURE: MATERIALS
• My online test.
PROCEDURE: STEPS
• Steps
– 1.Show family my online test.
– 2.Test my family members within my gene group.
– 3.Record the answers.
VARIABLES
• Constants: My test.
• Controlled variables: The statistics.
• Independent (manipulated) variable: My Family Members.
• Dependent (measured) variable: Color Blindness
DATA/OBSERVATIONS
• I had my family members take an online test to see if they have Color
Blindness problems.

CONCLUSION
• The occurrence of Color Blindness vs the general population does match up.
I tested against the 3 main Colorblindness's, and 2 people that have the
most trace have at least 2 types of Color Blindness. My hypothesis was
correct because 2 people have traces of Color Blindness and it matches my
statistics.
