BIO 123 PROBABILITY AND GENETICS LAB REPORT AND ANSWERS TEST YEAR 2023

BIO 123 PROBABILITY AND GENETICS LAB REPORT AND ANSWERS TEST YEAR 2023 1. Based on the parents' genotypes, what is the genotypic ratio expected from a monohybrid cross between the two parents for the trait? The genotype of both parents is Bb. Hence, after monohybrid cross, the genotype ratio can be determined as follows: The F1 generation will have genotype ratio BB:Bb:bb= 1:2:1. B b B BB Bb b Bb bb 2. Based on the genotypic ratio from question 1, what is the expected probability of each genotype? BB  25% Bb  50% bb  25% 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? 1. BB 2. Bb 3. bb BB = 15 Bb = 24 bb = 11 This study source was downloaded by from CourseH
