1)Construct the Punnett Square for theF2 generation of a cross between homozygous Round-yellow andhomozygous Wrinkled-green pea plants.

2)construct a branch diagram for the offspring of a crossbetween RRYyCc and rrYYCc pea plants

3. In one of Mendel’s dihybrid crosses heobserved the following F2 plants:

?315 round yellow 108 roundgreen 101 wrinkled yellow 32wrinkled green

Analyze these data using theX2 test to see if:

a. they fit the expected 9:3:3:1 ratio

b. the round:wrinkled data fit a 3:1 ratio

c. the yellow:green data fit a 3:1 ratio
