You Have Two True Breeding Strains Of Pisum Sativum With Regard To Three Characters Seed Shape Stem Length And Seed P 1 (45.76 KiB) Viewed 90 times

You have two true-breeding strains of Pisum sativum with regard to three characters: seed shape, stem length, and seed pod shape. One strain has round seeds, dwarf stems, and inflated seed pods. The other strain has wrinkled seeds, tall stems, and constricted seed pods. Upon crossing the two strains, all of the progeny have round seeds, tall stems, and inflated seed pods. Answer the following questions about the cross if you were to next interbreed the round/tall/inflated progeny: a. Show the branch diagram to predict the phenotypic ratios that you would expect to observe in the F₂ generation. (NO PUNNETT SQUARES) b. Indicate how many terms there would be in a x² analysis of the F₂ data and how many degrees of freedom you would have in your analysis.
