Is the allele for a scalloped wing in the fruit fly dominant or recessive to the wild type?

The scalloped wing allele in Drosophila melanogaster is considered to be a recessive allele. This means that an individual must inherit two copies of the allele, one from each parent, in order to exhibit the characteristic scalloped wing phenotype. If an individual only inherits one copy of the allele, they will have a wild type wing phenotype.

In terms of dominance, the allele for a scalloped wing in the fruit fly is recessive to the wild type. This means that the wild type allele is dominant and will mask the effects of the scalloped wing allele when present in an individual. Only when an individual has two copies of the scalloped wing allele will the characteristic phenotype be expressed.
