Thumb Dominance free essay sample

This experiment will determine whether for thumbs of clasped hands is a relationship between R-handedness or left handedness and which thumb is clasped on top of the other thumb. Question: * Does one inherited trait always influence another closely related trait? Research Reiss M. The genetics of hand-claspinga review and a familial study. Ann Hum Biol 1999 Jan-Feb; 26(1):39-48 Hand-clasping refers to the preferential tendency for individuals to clasp the hands together. This paper reviews the previous literature on family data and twins, and reports new data. In this study about 55% of the population are left-hand-claspers, 44% are right-hand-claspers, and the remaining 1% report that they have no preference or are indifferent. Familial data suggest that hand-clasping may be under genetic control: although the data do not fit any straightforward recessive or dominant Mendelian model, they are compatible with the type of model invoking fluctuating asymmetry which has been used to explain the inheritance of handedness and arm-folding.

Table 2: consists of all the data compiled Table 2: consists of all the data compiled Conclusion This experiment was more interesting than I expected. At first I thought that everyone that was right handed would be left hand dominate and the opposite if they were left handed. I was intrigued to find out that this isn’t the case, after testing the first few subject I released that there are some people that don’t even naturally cross their thumbs, they just naturally place their thumbs side by side. Another interesting conclusion was my parents, I just assumed that the results would be the same as mine but they were completely opposite.
