Ask a New Question
Menu

Start making a list of ten people whom you can contract. 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 a 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 brief paragraph to explain how your findings illustrate genetic diversity in humans.

Sample List of Ten People

| Name | Handedness | Tongue Rolling | Earlobes | Dimples | Freckles | Hair Type | |----------------|-------------|----------------|---------------|---------------|---------------|--------------| | Alice | Right | Yes | Detached | Yes | No | Curly | | Bob | Left | No | Attached | No | Yes | Straight | | Charlie | Right | Yes | Detached | Yes | No | Straight | | Diana | Right | Yes | Attached | Yes | Yes | Curly | | Edward | Left | No | Detached | No | Yes | Straight | | Fiona | Right | Yes | Detached | Yes | No | Curly | | George | Left | No | Attached | Yes | Yes | Straight | | Hannah | Right | Yes | Detached | No | Yes | Curly | | Ian | Left | No | Detached | Yes | No | Straight | | Jenny | Right | Yes | Attached | No | Yes | Curly |

Visualization: Genetic Diversity Chart

A simple way to visualize the data is with a bar chart that indicates the counts for each category.

Bar Chart Data

  • Handedness

    • Right: 6
    • Left: 4

  • Tongue Rolling

    • Yes: 6
    • No: 4

  • Earlobes

    • Attached: 4
    • Detached: 6

  • Dimples

    • Yes: 6
    • No: 4

  • Freckles

    • Yes: 5
    • No: 5

  • Hair Type

    • Curly: 5
    • Straight: 5

Brief Explanation of Findings

The findings illustrate genetic diversity within this small human sample set through various inherited traits. For example, six individuals exhibit right-handedness while four are left-handed, highlighting the commonality of right-handedness in the population. The ability to roll the tongue, which is a genetic trait influenced by dominant and recessive alleles, shows an even split between those who can and cannot. The presence of attached and detached earlobes, along with the varied occurrences of dimples, freckles, and hair type, further demonstrates the genetic variation present within this population. These traits reflect the complexity of human genetics, as many of these characteristics arise from multiple genetic interactions, contributing to the diversity observed in the broader human population.
