You are running a nursery for garden peas at Baton Rouge, and you have two pure-bred garden pea strains: Yellow Wrinkled [YYrr] and Green Round [yyRR]. You know that Yellow is dominant to Green, and also that Round is dominant to Wrinkled. One customer dropped by and asked about one particular pure-bred strain, Yellow Round [YYRR]. You promised to that customer that you could generate that strain next year through the following breeding experiments.
I. Crossing pure-bred Yellow Wrinkled with Green Round
II. Self-crossing F1 progeny
III. Screening pure-bred Yellow Round among the F2 progeny

What is the genotype for F1 progeny?

A. YYrr
B. rrYY
C. YyRr
D. yyrr
E. none of the above

The cross was done between pure-bred Yellow Wrinkled and Green Round plants. The genotype of the pure breeding yellow wrinkled parent plant: YYrr. The genotype of the pure breeding green round parent plant: yyRR.

A cross between YYrr and yyRR would obtain the progeny in the following ratios:

YYrr x yyRR= All YyRr (yellow and round)
