Genetics Practice 1: Basic Mendelian Genetics
Six genetics problems are to be solved by junior geneticists. Empty Punnett squares are provided for them to plant the parents' alleles and determine the genotype, phenotype, and frequency of offspring. All of the problems involve actual...

7.012 Genetics Section Problems
A set of phenotypes is listed for mice, flowers, blood type, and plants. For each, biology buffs analyze the percentages of phenotypes in the offspring and then identify the genotypes of the parents. This is a different approach to...
Curated OER
"Easter" Egg Genetics
Using plastic Easter eggs to represent parent phenotypes, genetics enthusiasts simulate the passing of alleles. They record the phenotype of each half of the egg, one representing the mother's and one representing the father's. They...

Dihybrid Cross Punnett Squares
In this dihybrid cross worksheet, students complete two punnett squares for the cross of two traits. They determine the genotypes, phenotypes and phenotypic ratios of the offspring.

Incomplete Dominant and Codominant Traits Worksheet
A two-page instructional activity provides seven Punnett squares for practice in determining genotypes and phenotypes. Each is an example of incomplete dominance or codominance. After your bright biologists have mastered Punnett squares,...
Curated OER
Genetics Problems Worksheet
In this genetics problems worksheet, high schoolers solve 20 problems by completing crosses using Punnett squares in order to predict the probability of genotypes and phenotypes of offspring.

Allele and Phenotype Frequencies in Rock Pocket Mouse Populations
In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...
Curated OER
Human Genetic Disorder Probabilities
In this genetic disorders worksheet, high schoolers complete punnett squares for six different human genetic disorders. They predict the outcome of the offspring including the phenotypes and genotypes of each.
Curated OER
Pea Plants Dihybrid Cross
In this dihybrid cross worksheet, students are given four crosses to complete using punnett squares. They determine the genotypic and phenotypic ratios of the offspring.
Curated OER
Natural Selection of Strawfish
A sequence of pictures accompany a few statements that help define the differences between phenotype and genotype. The slides must be used to accompany a lecture as they do not really explain any concepts. The 5th slide is the most...
Curated OER
Biology-Genetics
Students predict the probable mode of inheritance from a pedigree diagram showing phenotypes. They study the genetic basis for Mendel's laws of segregation and independent assortment. They give a Power Point slide show demonstrating the...

Using the Internet to Do Punnett Squares
What a fun way to explore Mendelian Genetics! Using a computer connected to the Internet, beginning biologists construct and use Punnett squares of monohybrid crosses to explain how genetic traits are passed to offspring. Other websites...
