**Category:** Genetics  
**Subtype:** Mendelian inheritance and genetic variation  
**Problem Description:** This problem involves a plant species with two traits (height and flower color) governed by multiple alleles. It examines the genetic outcomes of a cross between two plants (AaBb x AaBb) and the resulting F1 and F2 generations. The problem asks how many statements about the genotypes and phenotypes in these generations are correct, considering the effects of a chemical (colchicine) on meiosis and the potential for mutations.  

**Key Points:**
- The traits are controlled by two genes with complete dominance.
- The F1 generation is produced from a specific cross.
- The F2 generation results from random mating of F1 plants.
- The problem includes statements about the maximum number of genotypes and phenotypes in the F1 and F2 generations, requiring analysis of genetic combinations.
