What genetic basis of erminette pattern is suggested | Homework Help
Q1. Two species of zooplankton (Daphnia and Bosmina) are both limited by availability of their food (phytoplankton). When grown without Daphnia, Bosmina reaches an equilibrium density of 1000 individuals/liter and drives phytoplankton concentrations down to 30 cells/ml (i.e., at [phytoplankton]>30 cells/ml, Bosmina shows positive growth). In the absence of Bosmina, Daphnia reaches a density of 50 individuals/liter and drives phytoplankton concentrations down to 10 cells/ml. You now grow Daphnia and Bosmina together. Suppose they remain limited by phytoplankton.
Q2. Erminette fowls have mostly light-coloured feathers with an occasional black one, giving a flecked appearance. A cross of two erminettes produced a total of 48 progeny, consisting of 22 erminettes, 14 blacks, and 12 whites. What genetic basis of erminette pattern is suggested? How would you test your hypothesis?
