**Category:** Genetics  
**Subtype:** Genetic Linkage  
**Problem Description:** Determine the frequency of the gamete type "Ab" in a given organism with a specific genotype and known genetic distance between two genes.  

**Summary:** You have an organism with the genotype \(\frac{\mathrm{AB}}{\mathrm{ab}}\) and the genes A and B are 40 centimorgans (cM) apart. The problem asks you to find out what percentage of the gametes produced will be of the type "Ab." The options provided are 40%, 60%, 20%, and 30%.
