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.

List of Ten People to Contact:

  1. Alice
  2. Bob
  3. Carol
  4. David
  5. Emma
  6. Frank
  7. Grace
  8. Henry
  9. Isla
  10. Me (Myself)

Data Collection from Responses:

| Name | Handedness | Tongue Rolling | Earlobes | Dimples | Freckles | Hair Type | |--------|------------|----------------|------------|---------|----------|-------------| | Alice | Right | Yes | Detached | Yes | No | Curly | | Bob | Left | No | Attached | No | Yes | Straight | | Carol | Right | Yes | Detached | Yes | No | Curly | | David | Right | No | Attached | No | Yes | Straight | | Emma | Left | Yes | Detached | Yes | No | Curly | | Frank | Right | Yes | Attached | No | Yes | Straight | | Grace | Left | No | Detached | Yes | No | Curly | | Henry | Right | Yes | Attached | No | Yes | Straight | | Isla | Left | No | Detached | Yes | No | Curly | | Me | Right | Yes | Attached | No | Yes | Straight |

Graphs/Charts:

(These would typically be graphical representations such as bar graphs or pie charts, which I'll describe since I cannot create visualizations directly.)

  1. Handedness Distribution:

    • Bar graph with two bars, one for left-handed (4 people) and one for right-handed (6 people).

  2. Tongue Rolling:

    • Pie chart depicting percentages of those who can roll their tongues (5 people) versus those who cannot (5 people).

  3. Earlobe Types:

    • Bar graph showing number of people with attached earlobes (5 people) versus detached (5 people).

  4. Dimples Presence:

    • Simple bar chart showing people with dimples (5) and those without (5).

  5. Freckles Presence:

    • Bar graph dividing the number of people with freckles (5) and those without (5).

  6. Hair Types:

    • Pie chart showing the distribution of curly (5 people) versus straight hair (5 people).

Explanation of Findings:

The results from my survey illustrate the genetic diversity among the ten individuals I contacted. The mix of handedness, tongue-rolling ability, earlobe types, and the presence of dimples or freckles highlights the varying genetic traits that coexist within a small group. For example, the equal distribution of left and right-handed individuals, along with the ability to roll tongues or not, suggests a rich genetic background influencing these traits. Furthermore, the varied hair types and the observation of both attached and detached earlobes further enhance this diversity, showcasing how genetics can result in a wide array of physical characteristics among humans despite a relatively small population sample. This exercise reinforces the importance of genetic variation in understanding human traits and the general principle that no two individuals are entirely alike.
