Answer

Brief Explanations:

Mendel's cross of true - breeding parents (one with straight wings, genotype SS and one with curly wings, genotype ss) gives an F1 generation with all heterozygous (Ss) and straight - winged due to dominance. When F1 generation self - crosses (Ss x Ss), the F2 generation has a 3:1 ratio of straight - winged (SS or Ss) to curly - winged (ss) according to Mendelian genetics. The P generation has parents with opposite traits, so it has straight and curly wings.

Answer:

The P generation has straight wings and curly wings. The F1 generation has all straight wings. The F2 generation has straight wings and curly wings.
