You are a zoologist working with Giraffes. Their main traits are: Grey tongues (G*), Rudimentary Horns (R*), Long necks (L*). You perform the following testcross with an individual with recessive versions of all 3 of the traits.

Question
**Zoology and Genetics: Studying Giraffe Traits** As a zoologist focusing on giraffes, you are analyzing specific traits: Grey tongues (G\*), Rudimentary Horns (R\*), and Long necks (L\*). In your research, you conduct a test cross using an individual with recessive versions of all three traits. **Parental Cross:** - Parental Generation (P): G\* R\* L\*/G\* R\* L\* x G R L/G R L **First Filial Generation (F1):** - All identical: G\* R\* L\*/G R L **Results from Test Cross Progeny:** | Progeny Count | Traits | |---------------|-------------------| | 2021 | G R L | | 1987 | G\* R\* L\* | | 600 | G\* R L\* | | 444 | G R\* L | | 125 | G R L\* | | 122 | G\* R\* L | | 7 | G\* R L | | 1 | G R\* L\* | **Total Progeny: 5307** (Note: Report averages or ratios to one decimal place if necessary; i.e., 2.3) This table provides an overview of the trait combinations observed in the test cross progeny, helping in understanding the inheritance patterns of these characteristics in giraffes.
