Question

A scientist is studying fruit fly wings. Straight wings are dominant, and curly wings are recessive. Which statement correctly describes the F1 generation if a straight-winged parent is crossed with a curly-winged parent and if both parents are true breeding?

Answer 1

In the F1 generation, the child will have straight wing as dominant trait will show its characteristic unlike the recessive trait.

Answer 2

When a fruit-fly straight winged parent is crossed with a curly winged parent and the straight winged are dominant and curly winged are recessive then in the F1 generation the child will have the straight winged. Because straight winged are dominant character. According to Mendel's principle of inheritance, when two alternative factors come together in an organism only one of them called dominant is expressed while the other factor of the pair called recessive remains unexpressed.
