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. P: G* R* L*/G*R* L* x GRL/GRL F1 (all identical): G* R* L*/G RL Test Cross Progeny 2021 GRL 1987 G* R*L* 600 G R L* 444 G R* L 125 GR L 122 G*R* L 7 G RL G R L* Total progeny= 5307
