Two pea plants are crossed. One ishomozygous for white flowers and the other isheterozygous for purple flowers. Both are heterozygous for being tall plants. In pea plants, tall is dominant to short, and purple flowers are dominant to white.

Fill out the table below for the probability of each possible phenotype. Report probability as a decimal rounded to four places (e.g. 0.1250, not 1/8 or 12.5%).

In a population of 150 pea plants, there are 50 tall-purple plants, 18 short-purple plants, 62 tall-white plants, and 20 short-white plants. In order to test if the two traits are experiencing independent assortment researchers would perform a chi squared test.

The (null/alternative)hypothesis states that the two genes are independently assorted while the(null/alternative)hypothesis states the two genes are dependent.

What is your calculated Chi Squared statistic?

• When performing a contingency table,do not round your expected values!!
• Report your calculatedX²rounded to four decimal places

What is the corresponding P value?

• Use the formula=1-(CHISQ.DIST(X²,df,TRUE)) to convert calculatedX^{2into a P value}
• Report your answer rounded to 4 decimal places

Do youfail to rejectorrejectthe null hypothesis?
