Steps in the process Step 1: Studied dominant and recessive traits. Step 2:We surveyed everybody in class and recorded the data. The 7 traits surveyed in this project: Ear lobe, white forelock, thumbs, pinkys, color blindness, mid-digit hair, and dimples. Step 3:Analyzed the project data to find the percent of people showing the dominant and recessive phenotypes for each trait. Step 4:Went to excel and made a graph of the traits. In our class, 19 students were surveyed about traits. The traits that were surveyed were: earlobes, white forelock, dimples, thumbs, pinkies, mid-digit hair, and red/green color blindness. For earlobes: free(d)14/19: attached(r) :5/19. Dom. White Forelock: 0/19with(D) :19/19 w/out(R) Recessive Dimples: with(d)4/19 :without(r):15/19 Recessive Thumbs: straight(d)4/19: bent(r):15/19 Recessive Pinky: bent(d)7/19: straight(r):12/19 Recessive Mid-digit hair: 19/19 with (D): 0/19w/out(r) Dom. Red/Green color blindness: 19/19 normal vision Dom. With dimples is the dominant trait. Without dimples is the recessive trait. The recessive trait was the most common. The recessive trait, the attached earlobes, was more prevalent in this survey. However, in our class 14/19 were dominant, having detached earlobes. In the whole study recessive traits were more common.. Pinky genetic graph The recessive, straight pinkies, trait was the prevalent in this case, though the dominant trait, bent, was still showing. By Abby, Maddy, Sarah, Malik, Brett, the wonderful people! recessivedominant Mid-digit hair Students with out mid-digit hair represented the recessive trait. This trait was more common in this study than the dominant trait, people with mid-digit hair. There are 47% Curved thumbs which is recessive and 54% straight which is dominant. We have the hitch hiker trait! (curved) CurvedStraight The recessive traits appeared most often overall in this study. Conclusion Conclusions When Comparing our class to the overall survey of people studied, the recessive traits were still prevalent, but we had 4 recessive traits and 3 dominant traits. The overall project study showed 5 recessive and 2 dominant traits. In conclusion, the Recessive traits were prevalent. Ideas for the future In the future, wed like to see the survey include cleft chin and widows peak. Thanks for allowing us to do this project. We learned a lot doing this project and studying this genetic unit.
