2/5/15 : Probability and Inheritable Traits
Standards:
HS-LS3-3. Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population
Objective: To understand probability. To review how traits can be dominant or recessive and how they appear in populations.
Materials:
Procedure:
Part 1: Probability
Part 2: Class Traits
1. Using the Class Traits Allele Lab worksheet, go through the list of dominant and recessive alleles.
a. For each trait have students raise hands and take a count of the number of students with that trait. Then determine the percentage
2. Have students create a graph with the class data
a. Collect Graph
3. Have students complete Analysis Questions from Lab Sheet
