Crossing a normal size wheat with a dwarf wheat gives 100% intermediate size plants in F1. It is
assumed that only one gene is involved in this trait.
a) One allele has an incomplete dominance
b) The test cross carried out on F1 will give an offspring with a homogeneous phenotype
(intermediate)
c) One allele has a penetrance of 50%.
d) One allele is lethal
(e) No good answer
f) The test cross made on F1 will give an offspring with 2 different phenotypes (intermediate and
dwarf)
g) The test cross made on the F1 will give an offspring with 3 different phenotypes (normal,
intermediate and dwarf)
