In fruit flies, straight wings are dominant and curly wings are recessive. what will the generations look like? assume that mendel’s method of crossing two true breeding parents with opposite traits is followed.

Mendel explained the inheritance of traits and discovered that genes exist in several forms, called alleles. Every organism carries 2copies of every gene. Throughout reproduction process, one of the sequence copies is at random incorporated into every sex cell. Once the male and feminine gametes unite at fertilization, the gene copy is restored to 2. Completely different alleles might coexist in the organism. Throughout the production of gametes, they become independent from one another without being altered by coexistence.

Therefore, according to Mendel’s method, in fruit flies, straight wings are dominant and curly wings are recessive:
                                                                   The P generation will have straight wings and curly wings. Whereas, the F1 generation will have all straight wings. And the F2 generation will have straight wings and curly wings.
