Verified
You collect the following data on genotypes for a sunflower population: AA: 40, AB: 20, BB: 40. Based on Hardy-Weinberg predictions you expected the following numbers: AA: 25, AB: 50, BB: 25. Which of the following is a plausible explanation for the deviation?
A) balancing selection
B) negative frequency-dependent selection
C) inbreeding
D) genetic drift
Negative Frequency-Dependent Selection
Negative frequency-dependent selection occurs when rare genotypes have a fitness advantage simply because they are rare, helping to maintain genetic diversity within populations.
Pleiotropy
The genetic phenomenon where a single gene influences multiple phenotypic traits, demonstrating the complex nature of gene action.
Foraging Strategy
The behavioral patterns and techniques employed by animals, including humans, to find and gather food.
- Understand the importance and processes involved in genetic drift and natural selection, along with their contributions to the genetics of populations.
- Understand the subtleties and intricacies involved in genetic diversity, encompassing the impacts of migration, mutation frequencies, and selective forces.
