Punnett Squares with Piebald Deer
Explore the science behind Earth's amazing diversity of life with this instructional activity on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett squares to determine the...
Curated OER
Probability and Genetics
Learners determine the offspring from a genetic cross. In this biology lesson, students use Punnett squares to find probability. They explain how genes are passed from parents to offspring.
Curated OER
50:50 Chances
Third graders reinforce the probability of gender by uising a coin toss, as they continue to search for the answers to genetics questions by using mathematical expectations of probability.
Curated OER
Designer Genes
Students view a video on DNA. They discuss mitosis, meiosis and fertilization. They use strips of paper to simulate fertilization and analyze the genotype and phenotype of the combined chromosomes.
