Avariety of pure-breeding snapdragons produces a tall plant with green seeds (wwss). a second variety of pure-breeding snapdragons produce a short plant with white seeds (wwss). the two varieties are crossed, and the resulting seeds are collected. all of the seeds are green and when planted, they produce all tall plants (wwss). these tall f1 plants are allowed to self-fertilize. the results for seeds and plant height in the f2 generations are as follows. what is the х2 value, and the degrees of freedom for this experiment? f2 plant phenotypeobserved # green seed, tall565 white seed, tall180 green seed, short180 white seed, short75 total1000 a. х2 = 52.6, df = 1 b. х2 = 52.6, df = 4 c. х2 = 52.6, df = 3 d. х2 = 3.1, df = 4 e. х2 = 3.1, df = 3 f. х2 = 3.1, df = 1
