Science: Genetic Probability

by Texas Instruments

Overview

Use the SciTools App to simulate a Punnett square. Make predictions about genetic crosses. Learn about the following concepts; genes, alleles, dominant alleles, recessive alleles, homozygous individuals, heterozygous individuals, phenotypes, and genotypes.

Key Steps

Students use the random number generator to create lists that will contain the alleles for each of the 200 gametes of two parents and then combine the lists to represent 200 offspring.
Students then use the SciTools App to simulate a Punnett Square by representing the data generated in a histogram and then make predictions about the offspring.
