Maize (corn) is used for an experiment. The P1 cross of true breeding starchy purple x sweet colorless resulted in all starchy and purple F1. The F2 is as follows: 88 starchy and purple, 32 starchy and colorless, 29 sweet and purple, 17 sweet and colorless. How many genes and how many alleles per gene (respectively) are most likely involved? It's 4, 2 It's 1,4 It's 2, 2 It's 2, 4 It's 1,2

Question
**Maize Genetics Experiment**

In a genetics experiment involving maize (corn), a P1 cross was conducted between two true breeding plants: one starchy purple and the other sweet colorless. This cross resulted in offspring (F1 generation) that were all starchy and purple.

The F2 generation shows a variety of phenotypes with the following distribution:
- 88 starchy and purple
- 32 starchy and colorless
- 29 sweet and purple
- 17 sweet and colorless

**Question:**
Based on this F2 phenotypic ratio, how many genes and how many alleles per gene (respectively) are most likely involved in determining these traits?

**Options:**
- It's 4, 2
- It's 1, 4
- It's 2, 2
- It's 2, 4
- It's 1, 2

**Analysis:**
To determine the genetic involvement, consider the ratio and variety of F2 phenotypes. This information can help in deducing the number of genes and alleles contributing to the traits observed.
