1. You have made the following cross:



RRTT xrrtt

Red seeded, TallWhite seeded, short



F1:RrTt

Red seeded, Tall



F2:663 Red seeded, Tall : 87 Red seeded, short : 85 white seeded, tall : 165 white seeded, short




Assuming independent assortment (no linkage), what is the correct genetic ratio to consider for F2 segregation?
Test your hypothesis using a Chi Square test.













Assuming linkage, what is the crossover distance between the loci for red seed color and tall plants?
