The Genetics of Frizzle Frazzle Chicks
Frizzle feathers in chickens is the result of a dominant allele. Practice crosses between different types of chickens, by completing Punnett squares.

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.

Pedigree Analysis – AP Bio
Designed for biology students studying genetics. Determine the inheritance pattern for human disorders, like Tay-Sachs or Marfan Syndrome.

Horse Genetics
Practice genetic crosses with horse traits. The gait-keeper gene controls whether a horse will trot or pace and the flaxen gene determines mane color.

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 can then be compared to Punnet square expected results. Popsicles should be made in advance, the set contains a male and female set with the genotypes…
