How Much Alike Are We?

Activity Description:

Students will decide on (10) specific observable physical traits that are passed on through the heredity process. Students will conduct a survey, collect data, organize information into a chart, and compare data to national statistics. Students will then write a conclusion how their data compares with national averages.

Time Needed: 3 days with 30-45 minutes blocks of time

1st Day - Determine the (10) specific observable physical traits used in the survey.

2nd Day - Conduct survey and collect data.

3rd Day - Analyze data and compare with national averages.

Procedure:

Day 1

1. Group students into cooperative groups of 4-5 students per group.

2. Have a class discussion reviewing physical attributes that are inherited.

3. As a class, determine the (10) specific observable physical traits. These could include hand span, dimples, Ôhitch-hikersÕ thumb, straight thumb, attached ear lobs, unattached ear lobs, freckles, widowÕs peak hairline, naturally curly hair, ability to roll tongue, taste PTC (Phenylthiocarbamide) test paper, right or left handedness.

4. Have students prepare a chart for collecting data from among the schoolÕs 5th grade population.

Day 2

1. Collect data using the schoolÕs 5th grade population.

2. Record data in the chart.

Day 3

1. Have each cooperative group total each observable trait category and predict how their data compares with class and national frequencies.

2. As a class, combine the data and calculate the frequency in a percent and compare this with national data.

3. Have students write a conclusion relating their collected data to national averages.

4. Cite two examples how heredity plays out in real life.

National Averages

Trait	Frequency Form 1	Frequency Form 2
Gender	Female ∆ approximately 50%	Male ∆ approximately 50%
Earlobes	Unattached (free) ∆ more frequent	Attached ∆ less frequent
Thumb extension	Straight thumb ∆ 64-75%	HitchhikerÕs thumb ∆ 25-36%
Tongue rolling	Can roll tongue ∆ 65%	Cannot roll tongue ∆ 35%
Cheek dimples	Dimples ∆ more frequent	No dimples ∆ less frequent
Handedness	Right handed ∆ more frequent	Left handed ∆ less frequent
Hand clasping	Left over right ∆ 55%	Right over left ∆ 44%
Hair curl	Curly hair ∆ more frequent	Straight hair ∆ less frequent
PTC Tasting	Can taste PTC ∆ 70%	Cannot taste PTC ∆ 30%
Hairline	WidowÕs peak ∆ more frequent	Straight hairline ∆ less frequent
Color vision	Normal color vision ∆ females 100%; males 92%	Color blind ∆ males 8%
