Question

The non-wild-type alleles are k (clipped wings), l (long tail), and m (magical powers). The parental stocks are homozygous doubly recessive flies of genotype k+/k+ · l/l · m/m and homozygous singly recessive flies of genotype k/k · l+/l+ · m+/m+. From this cross, triply heterozygous progeny of genotype k/k+ · l/l+ · m/m+ are obtained, and females of this genotype are testcrossed to triple recessives of genotype k/k · l/l · m/m. The genotypes determining the eight progeny types from this testcross (CROSS C) are shown here with their numbers, out of a total sample of 1,572 flies. What is the correct order of the genes? 

What number of progeny for each genotype would you predict in the case of independent assortment?

### Gamete Distribution Data

The table below details the distribution of different gametes and their respective numbers:

| **Gametes** | **Number** |
|-------------|------------|
| k⁺ l⁺ m⁺    | 621        |
| k l m       | 608        |
| k l⁺ m⁺     | 103        |
| k⁺ l m      | 109        |
| k⁺ l m⁺     | 64         |
| k l⁺ m      | 57         |
| k⁺ l⁺ m     | 3          |
| k l m⁺      | 7          |

**Total: 1572**

This table categorizes the various types of gametes based on their genetic markers, denoted by the presence (⁺) or absence (absence of the sign) of specific alleles k, l, and m. The **Number** column indicates the frequency or count of each type of gamete observed in the data set.

### Insights
- The most frequent gamete is `k⁺ l⁺ m⁺` with a count of 621.
- The least frequent gamete is `k⁺ l⁺ m` with a count of 3.
- The total number of gametes recorded is 1572, indicating a comprehensive sample size for the study.

### Educational Significance
Understanding the distribution of gametes is essential for grasping the fundamentals of genetic inheritance. This data can aid in teaching concepts such as:
- Mendelian inheritance
- Allelic frequencies
- Genetic variability

This tabulated data is useful for students and educators in illustrating how different combinations of alleles can occur and their relative frequencies within a population sample.
