In a particular strain of tulip, normal flowers have a yellow color due to a dominant allele (Y) for a gene on
chromosome 3. A recessive allele (y) for this gene results in a white flower color. A dominant allele for a
different gene on chromosome 3 results in red spots on the flower petals (R), whereas a recessive allele for this
gene (r) results in no red spots. These two genes are located 40 LMU apart. A true-breeding tulip with yellow
flowers containing red spots is crossed with a true breeding tulip with solid white flowers (no red spots). All of
the offspring produce yellow flowers with red spots. Indicate the probabilities of all possible phenotypes in the
offspring of an F1 tulip (dihybrid producing yellow flowers with red spots) and a tulip producing white flowers
with red spots, one whose parents produced flowers with no red spots.
In Drosophila, normal (wild-type) body color is gray. A recessive allele for a particular autosomal gene results in
a purple body color (p). A recessive allele for a different gene on the same chromosome results in a wingless fly
(w). The two genetic loci are 16 LMU apart. A true-breeding purple fly with normal wings is crossed with a true
breeding gray fly with no wings. All of the offspring are gray with normal wings. Indicate the probabilities of all
possible phenotypes in the offspring of an F1 dihybrid fly and a purple fly with wings that is heterozygous for
the gene determining the presence of wings.
