research essay and my survey questions

Let me guess, you are a right-handed person? Have you ever thought about how unique being left handed is? In this society right handed is more dominant than being let handed. Many people don’t realize how much being left handed effect on daily life. They do certain things with left hand but use their right hand as well. Years ago, being left handed was consider to be ill-omen. Which means if you were born being lefty you had the devil’s hand. In colonial day, being left handed could even get a person accused of witchcraft. As of today, about 12% of the world population is left handed. What makes them unique and different then right-handed people? Are they smarter then right-handed people? Do you wished you were left handed? What makes them left handed and you a normal person with right hand? research will find out the answer for these question in this research paper. Hopefully, the research conduct in this study will provide some insight into why are they left handed but not right and why are they the minority?

It’s still not proven what makes them left handed. But, Research believe that the lefties are the complex collaboration between genes and environment. Everyone thinks that being left handed is a good think because they are smart in everything. According to the global TCK care and education, “The human brain has two cerebral hemispheres, the left and the right. The left hemisphere processes things more in parts and sequentially, and is the center for language, science, mathematics, and logic. This left side of the brain is usually dominant, and because the left side of the brain controls the right side of the body, these individuals are right-handed.” (cite #1) The right side of the brain is the source of dram, art, music and feeling. In left handed individuals the right side of the brain is dominant which makes them a left handed. More than half lefties use their right hemisphere for language. However, many left handed people have speech issue, left handed people brain allow them to the process the language in more unique and creative way. Which is the reason why many lefties are smart in math.

To further understand more about this methodology, the research is doing a survey with16 participants, 8 females and 8 males. The participant are students from English 1101. Also, the research does and interview with the biology professor at the Dalton State. The survey has 19 questions over whether they use their left hand or right hand.

ADD CHART FOR THE SURVEY.

Next, the research survey 16 participants with 19 questions. One of them is: are you left handed or right handed? This question is at the beginning of the survey, and the answer are similar between males and females. According to the survey, “2 out of 8 females are left handed and all males are right handed” (English 1101 –cite#3) it seems like 2 out of 16 participants are left handed. This is very interesting because when the research asked the participants that which arm is on top when they fold their arm in front of them, the number increased drastically. As of result 14 participants have their arm on the top even though they are right handed. So, the research concludes that even though they are right handed they still use their left hand for different thing.

To understand more about why they use their left hand and not right even though they are right handed, researcher interviewed the biology professor at Dalton State to find out more about this mystery. The professor at the Dalton State stated that “even though they are right handed they still the genes from their parents or their ancestors who were left handed, the way to prove this is through the Mendel theory” (cite 3) this theory involves the passing of discrete units of inherence, or genes form parent to offspring. So, research did and experiment on his parents, both of his parents are right hand but one of them have the gene for left hand. To understand this claim more thoroughly researched has created a chart.

R= RIGHT HAND GENE

l= LEFT HAND GENE

In order to be a left handed, both of your parents need to have a gene for left hand. As you can see, capital “R” takes over the lower cases “l” which shows that right hand gene takes over the left hand and that’s how you become right hand even though you have left hand gene. However, even though both of your parents are right handed and have a gene for left hand, you have a 25% chance of being left hand. According to the biology professors, “both of the parents need the left-hand gene to have an offspring of left hand, even though they are right handed” (cite 4).

Once again, being left hand is very rare and unique. With the help of a professor at the Dalton state, the Mendel theory proved that even if both of your parents are right handed, and their ancestor were left handed, you would still have a chance of being left handed but the chances are very low. According to the survey there were few students who were left handed, but both of their parents have a dominant trait. If none of your parents have a left-hand gene then you will be right hand and so will your children’s, until someone in your family marries someone who is left handed. Right hand gene is very common and that’s why it’s very dominant over the left-hand gene. Which makes it harder for people to get left hand offspring.
