Genotype and phenotype of fruit fly: The genotype refers to the entire hereditary information of an organism whereas phenotype refers to the physical character of an individual. The fruit fly is a heterozygous for eye color as it has both black eyes and red eyes.
Q. Why do fruit flies have different phenotypes?
Lucky for scientists, and maybe not so lucky for fruit flies, there are all kinds of ways that fly DNA can be mutated to create interesting looking flies. These different visible traits that result from mutated DNA are called phenotypes.

Q. What is the genotype of a fruit fly?
In fruit flies, the dominant V allele produces long wings, whereas the recessive v allele produces vestigial wings. Thus, flies with the genotype VV or Vv will have long wings, and flies with the genotype vv will have vestigial wings.
Q. What is the genotype of a male fruit fly?
The sex of the fruit fly Drosophila melanogaster is determined as follows: XX chromosomes give a female and XY give a male. The gene for bar eyes is recessive and located on the X chromosome. A male has a genotype RrTt.
Q. How can you determine a genotype?
Certain combinations of DNA nucleotides will create different genotypes, or pairs of traits. The traits represented in a genotype can be dominant or recessive, and will determine how that feature is expressed by the organism. To determine a genotype, you can use a Punnett square.
Q. Are brown eyes dominant in fruit flies?
Brown and sepia eyes are a result of a recessive gene and only occur when two sepia-eyed flies mate. The white-eyed fruit fly gene is recessive and typically is eliminated after mating with dominant-eyed fruit flies for two generations.
Q. Why do fruit flies fly at your face?
Although mosquitoes and other blood-feeding insects are attracted to the carbon dioxide we exhale, we know the insect sensory system also helps find exposed skin. Since the skin near our faces is often exposed, that’s one reason flies are always buzzing around your face and hands.
Q. Can fruit flies lay eggs in humans?
Semispecific myiasis Flesh flies, or sarcophagids, members of the family Sarcophagidae, can cause intestinal myiasis in humans if the females lay their eggs on meat or fruit.
Q. Do fruit flies go away on their own?
Once fruit flies take hold in your kitchen, they won’t go away on their own. A small family of fruit flies will quickly turn into Fruitflymageddon! Fortunately, you don’t have to put up with fruit flies. You can prevent an invasion, and quickly stop one too.
