Is the allele for long wings dominant or recessive?

Fruit Flies can have short wings or long wings. A homozygous long-winged fruit fly (A) mated with a homozygous short-winged fruit fly(B). The allele for long wings is denoted by L, and the allele for short wings is l.

The genotype for fly A is ______ and the genotype for B is________?

is a type of point mutation where just a single nucleotide is changed. This type of mutation causes no change in the protein that is produced.

Normal: AUG GCC TGC

met ala cys

Mutation: AUG GCT TGC

met ala cys

A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes.

Normal: AUG GCC TGC AAA CGC TGG

met ala cys lys arg trp

Mutation: AUG GCC GGC AAA CGC TGG

met ala arg lys arg trp
