Ask a New Question
Menu

Start by making a list of ten people whom you can contact. (You can include yourself on this list if you wish!) You will ask each person the following questions:

Are you left-handed or right-handed?
Can you roll your tongue?
Are your earlobes attached or detached?
Do you have dimples?
Do you have freckles?
Is your hair curly or straight?
Use this sample set to make a chart or graph to visually illustrate the genetic diversity of the population you have selected. After you have completed this illustration, write a brief paragraph to explain how your findings illustrate genetic diversity in humans.

Here's a list of ten people you could contact for this survey:

  1. Yourself
  2. Your mom
  3. Your dad
  4. Your sibling
  5. A close friend
  6. A neighbor
  7. A classmate
  8. A coworker
  9. An aunt or uncle
  10. A grandparent

Questions for Each Person

Here are example responses (hypothetical) for each of the ten people based on the questions provided:

| Person | Handedness | Tongue Rolling | Earlobes | Dimples | Freckles | Hair Type | |-------------|--------------|----------------|-----------|----------|----------|---------------| | Yourself | Right-handed | Yes | Detached | No | Yes | Straight | | Mom | Left-handed | No | Detached | Yes | No | Curly | | Dad | Right-handed | Yes | Attached | No | Yes | Straight | | Sibling | Right-handed | Yes | Detached | Yes | Yes | Curly | | Friend | Right-handed | No | Attached | No | Yes | Straight | | Neighbor | Left-handed | Yes | Detached | No | No | Curly | | Classmate | Right-handed | No | Attached | Yes | Yes | Straight | | Coworker | Left-handed | Yes | Detached | No | No | Curly | | Aunt/Uncle | Right-handed | Yes | Attached | Yes | Yes | Straight | | Grandparent | Right-handed | No | Detached | No | Yes | Curly |

Graphing Your Data

You can create a simple bar graph or pie charts to visualize the data collected. For example, you could have separate charts for each trait showing the counts of responses (e.g., how many were left-handed vs. right-handed). Alternatively, you could use a tally chart to capture the presence or absence of traits like dimples and freckles.

Explanation of Findings

The findings from this survey demonstrate the genetic diversity present within a small sample of the human population. For instance, in regard to handedness, we see a mix of left-handed and right-handed individuals, suggesting a varied genetic inheritance of this trait. Additionally, the presence and absence of features such as dimples and freckles further illustrate the diversity among individuals, reflecting the complexity of human genetics. Different combinations of traits (like curly or straight hair alongside earlobe types) further indicate that human beings possess a wide range of genetic variations, influenced by both genetic inheritance and environmental factors. This diversity is what contributes to the unique characteristics of each individual, highlighting the intricate nature of human genetics.
