What if, in moths, brown wings are incompletely dominant over white wings.  How would this alter the expected phenotypes in the offspring produced by the cross described in question #25?

Suppose that, in moths, brown wings are completely dominant over white wings.  In addition, straight antennae are completely dominant over crooked antennae.  Moth #1 is homozygous for the recessive form of wing color and antennae shape.  Moth #2 is heterozygous for wing color and homozygous for the dominant antennae shape.  If Moth #1 mates with Moth #2 to produce 16 offspring, how many of the offspring would you expect to have brown wings and crookedantennae?

Consider the pedigree shown below. Each individual in the pedigree has a number designation just to make it easier for you to refer to certain individuals in your answer, if you wish.  The trait shown in the pedigree above ____________ an X-linked recessive trait (i.e. a trait that has the same inheritance pattern as the red-green colorblindness trait we studied in one of our assignments). Hint: Take advantage of your scratch paper to work out your answer to this question.
