Question

Make Connections: The Hardy-Weinberg Principle and the Inheritance of Alleles When two individuals mate, the inheritance of aleles by the offspring is typicaly a dhance event that depends on which parental aleles come together during fertilization (elck on the figure below on the left. By looking at these chance events across an entire up the Handy-Weinberg principle (dick on the figure below on the right) Part A-Reviewing the inheritance of alleles Imagine that you are studying a gene (sets you expect to find inthe offspring of two R parents? What is the probability of producing an offspring with each of the possible genotypes? The figure shows how these probabilites can be calculated segregation of alleles into eggs alleles into sperm

Explanation / Answer

1. 50%

2. 50%

3. 25%

4. 25%

5. 25%

Answer 1 and 2 explanation : the probability of producing gametes is 50-50 chance. Just like when we toss a coin the probability of having heads or tails is 50-50.

Answers 3,4 and 5 explanation : the offspring may be of 4 different genotypes. They are RR, rR, Rr and rr. All of them have equal probability which accounts to 25% each.
