"Amoeba Sisters: Monohybrid Cross"

Master monohybrid crosses & Punnett squares with this genetics practice!

Amoeba Sisters - Punnet Square video Genotype The genetic make up (AA) Phenotype Traits shown (or appearance) Homozygous Both alleles match (both dominant for example) Recessive Weaker trait that hides Heterozygous Alleles are opposite (Aa) Dominant Stronger trait that shows up Allele Different forms of a gene Complete the Punnett Square below, given the following information: In a barn, you have 2 cows. One has spots and the other does not. Having spots is a dominant trait (S) to not having spots (s). Fill in the Punnett square.(Hint: make sure two letters are in each square.) Don't type in this box S S s Ss Ss s Ss Ss What percent of the cows offspring would have spots? 25% 50% 75% 100% What percent of the cows offspring would be spotless? 0% 25% 50% 75% What would be the genotype of the offspring? homozygous recessive heterozygous homozygous dominant What would be the phenotype of the offspring? Spotted cows Spotless cows
