In peas, the smooth seed S allele is dominant to wrinkle seed s
allele, the green seed allele Y is dominant to the yellow seed y,
and the tall plant allele T is dominant to the short plant allele
t. All three traits are unlinked (the genes are on different
chromosomes). A breeding cross between a tall plant with smooth
green seeds and a short plant with wrinkled yellow seeds produces
the following numbers of plants with four different combinations of
the traits:
smooth, green, tall: 2004 plants
wrinkled, green, short: 2011 plants
wrinkled, green, tall: 2007 plants
smooth, green, short: 2008 plants
The most likely genotype of the tall parent plant with smooth
seeds is ____(1)____ and the most likely genotype of the short
parent plant with wrinkled yellow seed is _____(2)_____.
(1)
a: SS, Yy, TT
b: Ss, Yy, Tt
c: Ss, YY, Tt

b: ss, yy, Tt
c: Ss, Yy, Tt
d: SS, YY, TT
