You are spending a summer in Austria following up on
some of Mendel's work. You are studying the inheritance of a
new mutant allele that causes white flower color (the dominant,
wild-type flower color is red). You are also working with a
recessive allele that results in dwarf plants relative to the wild-
type dominant tall condition. One plant (named plant A) is tall
with red flowers. When you test-cross plant A to a dwarf plant
with white flowers you count the following progeny: 94 tall red
flower; 86 dwarf white flower; 6 tall white flower and 14 dwarf
red flowers. A second plant (Plant B) also is tall with red
flowers. When you test-cross plant B to a dwarf plant with
white flowers you count the following progeny: 4 tall red flower;
6 dwarf white flower; 45 tall white flower and 45 dwarf red
flowers. If you cross plants A and B to each other, what
percentage of the progeny do you expect to be dwarf with white
flowers?
