DNA Coloring
In this activity, students color a DNA molecule according to directions that describe the base-pair rule and how the backbone of the molecule is composed of deoxyribose and phosphate …

Practice Problems: Genetics and Blood Types
This worksheet provides students with practice problems on multiple allele traits, specifically on how blood types are inherited. The problems focus on the ABO blood groups and students …
Analyzing Human Pedigrees
Biology students learn to analyze pedigrees as part of a unit on genetics. Pedigrees are usually learned soon after students have a grasp of Punnett squares and the concept …
Practice Genetics: Sex Linked Genes
Students learn basic Mendelian genetics by crossing traits from fruit flies and pea plants. In this extension, students can practice doing crosses that involve sex-linked traits, where the alleles …
Investigation: Modeling Independent Assortment & Dihybrid Crosses
If your class modeled inheritance using popsicle sticks, this activity builds upon that process. Here students must examine how two traits are inherited, revealing that each allele has an …
Investigation: Modeling Heredity with Popsicle Sticks
In this activity, you will use popsicle sticks to model the process of gamete formation and the combining of sperm and egg to create offspring. Results of the simulation …
