The vestigial gene is the trait most likely linked to having a curved wing in the fruit fly. Flies with vestigial wings cannot fly.
No! The eye of the octopus is a highly adaptive trait and better than the human eye because the nerves that go to the brain are not in the way of the retina as is the case in humans, A vestigial trait us a trait that is not used for it original purpose, such as the tail bone in humans.
Humans have tail bones are are vestigial. When humans stopped using tails, over several generations, they began to shrink, and now we are left with tail bones. However, there have been cases of people who were born with vestigial tails several centimeters long. An example of a vestigial organ is the appendix.
The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.

An X-linked recessive trait is coded for by a gene on the X-chromosome and is not dominant (is canceled out by the presence of a different allele). Example of X-linked recessive traits are; Haemophilia A & B and Duchenne muscular dystrophy.
A vestigial trait (i.e. organ, appendage, etc) is a remnant part of an organism that historically was very important but evolutionarily is no longer needed. For example, the tailbone on humans is considered vestigial because it serves little to no purpose, although at one point it most likely connected to a tail. Another example is the dew claw on a dog (the small, dangling claw on a dog's front paws). Clearly there's no use for it today, but at one point it may have served an important purpose for survival. appendix wisdom teeth tailbone male nipples xD body hair thymus gland the "tip" of your ear ear muscles
A recessive trait is one that will only be expressed when in the presence of two recessive alleles.
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.
Doing mathematics is definitely a learned trait.
