Genetic inheritance is being studied in a certain species of
plant in which orange flower color (O) is dominant to white
,3|Page
(o) and round leaf shape (S) is dominant to oval (s). A
true-breeding orange-flowered, round-leaved male plant
(Plant A) is mated with a true-breeding white-flowered,
oval-leaved female plant (Plant B) to produce dihybrid
offspring plant (Plant C). Assuming normal Mendelian
genetics and independent inheritance of these two traits,
which gametes might be produced by Plant C?
a. OoSs
b. OS
c. oS
d. Both OS and oS
e. Both OoSs and OS - ANSWER-d. Both OS and oS

strain is mated with a guinea pig from a true-breeding
white strain. The F1 progeny are all black. Two of the F1
progeny are mated with each other. What proportion of the
F2 progeny is expected to be white?
a. 1/2
b. 1/3
c. 1/4
d. 3/4 - ANSWER-c. 1/4
