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? The offspring will have two genes for straight wings. The offspring will produce only gametes that have genes for curly wings. The offspring will have one allele for straight wings and one allele for curly wings. The offspring will have only one kind of allele for the gene that determines wing type.

C. The offspring will have one allele for straight wings and one allele for curly wings.

Explanation:

This can be explained by assigning A - dominant allele for straight wings

a - recessive allele for curly wings

We can infer that

AA - straight-winged parent

aa - curly-winged parent

When we cross match we get:

Parental generation:     AA     x      aa

F1 generation:           Aa    Aa    Aa     Aa

This means the offspring will have one allele for straight wings and one allele for curly wings.

the answer is c the offspring

a community that experiences major changes undergoes progress

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
