Mendel imagined that seed color in pea plants is influenced by a gene with two alleles in which the allele
for yellow seeds (Y) is dominant over the allele for green seeds (y). What would Mendel predict the seed
colors would be from a cross of a male plant with the mixed Yy genotype with a female plant with the yy
genotype?
a. All seeds should be green.

Genetic inheritance is being studied in a certain species of plant in which orange flower color (O) is
dominant to white (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?

d. Both OS and oS
e. Both OoSs and OS - ANSWER-d. Both OS and oS

to be white?
a. 1/2
b. 1/3
c. 1/4
d. 3/4 - ANSWER-c. 1/4
