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.

What is the distance between G&R, G&L, R&L

**Genetic Study of Giraffe Traits - Test Cross Analysis** As a zoologist working with giraffes, the focus is on three main traits: Grey tongues (G^r), Rudimentary Horns (R^r), and Long necks (L^r). In this study, a test cross is performed with an individual that possesses recessive versions of all three traits. **Parental Generation (P):** - G^r R^r L^r / G^r R^r L^r × G R L / G R L **First Filial Generation (F1):** - All individuals are G^r R^r L^r / G R L **Test Cross Progeny Results:** | Number of Progeny | Phenotype | |-------------------|-----------------| | 2021 | G R L | | 1987 | G^r R^r L^r | | 600 | G^r R L^r | | 444 | G R^r L | | 125 | G R L^r | | 122 | G^r R^r L | | 7 | G^r R L | | 1 | G R^r L^r | **Total Progeny = 5307** **Notes:** - Please do not round answers. Leave them as 1 decimal point.
