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.

Sure! Here’s a simple example of how you could create a list of ten people and their responses to the questions. You can use this data to create a chart or graph.

List of People and Answers

| Person | Handedness | Can Roll Tongue? | Earlobes | Dimples | Freckles | Hair Type | |--------|--------------|-------------------|----------------|---------|----------|-------------| | 1 | Right-handed | Yes | Detached | Yes | No | Curly | | 2 | Left-handed | No | Attached | No | Yes | Straight | | 3 | Right-handed | Yes | Detached | No | Yes | Curly | | 4 | Right-handed | Yes | Detached | Yes | No | Straight | | 5 | Left-handed | No | Attached | Yes | Yes | Curly | | 6 | Right-handed | Yes | Detached | No | No | Straight | | 7 | Left-handed | Yes | Attached | Yes | No | Curly | | 8 | Right-handed | No | Detached | No | Yes | Straight | | 9 | Right-handed | Yes | Attached | No | Yes | Curly | | 10 | Left-handed | No | Detached | Yes | No | Straight |

Chart or Graph Ideas

  1. Bar Graphs:

    • Create a bar graph showing the number of people who are left-handed vs. right-handed.
    • Make separate bar graphs for traits like "Can Roll Tongue" (Yes/No), "Earlobes" (Attached/Detached), "Dimples" (Yes/No), "Freckles" (Yes/No), and "Hair Type" (Curly/Straight).

  2. Pie Charts:

    • You can use pie charts to represent the percentage of each handedness, tongue-rolling ability, earlobe type, etc.

Explanation of Findings

From my findings, it’s evident that there is significant genetic diversity within this small group of ten individuals. For example, while the majority are right-handed, there is a diverse representation of left-handed people as well. The variation in other traits, such as the ability to roll the tongue or the presence of dimples, shows that even in common characteristics like hair type and earlobe shape, there are different genetic factors at play among individuals. This diversity highlights how unique each person’s genetic makeup is, which reflects the broader genetic diversity found within the human population as a whole.
