Genetics Practice – Roan Cows with Horns
Practice genetics with cows! Cows can be horned (hh) or hornless. They can also be red, white, or roan colored.

Peas, Please! – A Practice Set on Mendelian Genetics
Students practice assigning genotypes (PP, Pp, or pp) to different traits based on whether the trait is dominant or recessive. They set up Punnett squares, and determine the phenotypic ratios of the offspring.

Case Study – The Genetics of Eye Color
A case study exploring the genetics of eye color. Students review a pedigree and examine the role of HERC2 and OCA2 in eye color inheritance.

Mutations and Evolution in Aquatic Mammals
Students examine a phylogenetic tree that reveals mutations found in aquatic mammals as evidence of convergent evolution.
-
Case Study: Dogs, SNPs, and Patellar Luxation
Students learn how a genetic polymorphism (SNP) is associated with a common problem in chihuahua dogs where their patella slips out of position.

Tasmanian Devil Karyotype (Remote Version)
Examine a karyotype showing the chromosomes of a Tasmanian devil. Arrange chromosomes and determine diploid number.

Corn Chi Square (remote)
This is the remote version of a classroom activity I do with corn ears. Students would count the kernels (smooth, wrinkled, purple, yellow) and determine if the ears of corn are the result of a dihybrid cross, RrPp x RrPp. This gives students the opportunity to apply statically analysis to data sets and determine if…
