Two Drosophila are crossed several times, with a total number of offspring of 106 females and 48
  males. There is too great a deviation from the expected 1:1 ratio for chance alone to account for the
  difference. What other factor could account for this difference? What will be an ideal response?
 
 

Question 2

  produces wild body colors, give the phenotypes expected and their frequencies for the following four
  crosses:
  (a) yellow female  wild male
  (b) wild carrier female  wild male
  (c) wild carrier female  yellow male
