**Category:** Genetics  
**Subtype:** Genetic Crosses  
**Problem Description:** Determine which genetic cross results in offspring with 48 different genotypes, given that no mutations occur.  

In this problem, you are asked to analyze different genetic crosses (mating combinations) to find out which one produces a total of 48 unique combinations of genes in the offspring. Each option presents a different combination of alleles (gene variants) for two parents, and you need to calculate the potential genotypes that can arise from each cross.
