Document Summary
Biology 207 - practice questions 7 - sex chromosomes. Question 2 (this is an old midterm question) in turkeys the bh-gene is responsible for leg morphology and the e-gene is responsible for feather colour. Wild type turkeys have strong legs and bronze coloured feathers. You are in charge of a flock of pure-breeding wild type female turkeys but a male turkey with weak legs and brown feathers sneaks in and impregnates all the females. In the next generation the males are all phenotypically wild type while all the females have brown feathers and strong legs: draw this cross showing the phenotypes and genotypes of the parents and the f1 turkeys. List the phenotypes and genotypes you would get from this cross. (3 marks)
