PROBABILITY AND GENETICS LAB REPORT AND ANSWERS
1. Based on the parents' genotypes, what is the genotypic ratio expected from a
monohybrid cross between the two parents for the trait?
2. Based on the genotypic ratio from question 1, what is the expected probability of each
3. Toss the coins together 50 times and keep a tally sheet while doing so. They can only turn
up as BB, Bb, or bb. Remember: each coin represents each parent and each toss can only
turn up one way, therefore, a parent can give only one gene of a pair. How many tally's for
each genotype did you get?
