Question

has two phenotypic traits you are interested in. ssive), Yellow (Dominant) or Green (Recessiv h traits (RrYyx RrYy), you have 556 progeny. as if these traits are independently assorted. lust like Mendel, you have grown a pea plant that has two Round (Dominant) or Wrinkled (Recessive), Yell After crossing two plants heterozygous in both traite First, calculate their expected progeny distributions as if these llowing results. Use Chi-Square Analysis and sther these traits do indeed display independent 3. After classifying your progeny. you observe the following results. Use Chis the p-value chart above to determine whether these traits do indeed a assortment. a. What is your df? b. What is your null hypothesis? Are the data consistent with your null hypothesis or can you reject the null hypothesis d. Provide evidence to support your case. Observed Values Expected Values (From Above) 315 Round, Yellow Seed 108 Round, Green Seed 101 Wrinkled, Yellow Seed 32 Wrinkled, Green Seed 556 Total Seeds

Answer 1

4) RrYy * RrYy

	RY	Ry	rY	ry
RY	RRYY( round, yellow)	RRYy ( round, yellow)	RrYY ( round, yellow)	RrYy ( round, yellow)
Ry	RRYy ( round, yellow)	RRyy ( round, green)	RrYy ( round, yellow)	Rryy ( round, green)
rY	RrYY ( round, yellow)	RrYy ( round, yellow)	rrYY( wrinkled, yellow)	rrYy ( wrinkled, yellow)
ry	RrYy ( round, yellow)	Rryy ( round, green)	rrYy ( wrinkled, yellow)	rryy( wrinkled, yellow)

the expected proportion of round, yellow= number of round, yellow/total number=9/16

expected proportion of round, green= number of round, green/total number=3/16

expected proportion of wrinkled, yellow= number of wrinkled, yellow/total number=3/16

expected proportion of wrinkled, green= number of wrinkled, green/total number=1/16

expected number of round, yellow= total number of progeny$\times$ expected proportion of yellow, round=556$\times$9/16=312.75

expected number of round, yellow= 313

expected number of wrinkled, yellow= total number of progeny$\times$ expected proportion of wrinkled, yellow=556$\times$3/16=104.25

expected number of wrinkled, yellow=104

expected number of round, green= total number of progeny$\times$ expected proportion of green, round=556$\times$3/16=104.25

expected number of round, green= 104

expected number of wrinkled, green= total number of progeny$\times$ expected proportion of green, wrinkled=556$\times$1/16=34.75

expected number of round, green= 35
