The wild type eye color of Drosophila melanogaster, commonly known as the fruit fly, is typically red. This red eye color is due to the presence of specific pigments produced by the fly's genetic makeup. Mutations can lead to different eye colors, such as white or brown, but red is considered the standard or "wild type."
What else can I help you with?
Is the white eye mutation in Drosophila was shown to be sex-linked and caused by a gene residing on chromosome x?
Yes, the white eye mutation in Drosophila is indeed sex-linked, as it is located on the X chromosome. This mutation is caused by a defect in the gene that codes for eye color, resulting in white eyes instead of the typical red color found in wild-type flies.
How did Morgan determine that the eye color in drosophila is an x-linked trait?
Morgan observed that certain eye color traits in Drosophila were inherited differently in males and females. By crossing Drosophila with different eye color phenotypes, he discovered that the gene for eye color is located on the X chromosome. This led to the conclusion that eye color in Drosophila is an X-linked trait.
Can fruit flies have red and white eyes?
Yes, fruit flies (Drosophila melanogaster) can have both red and white eyes due to genetic variations. The red eye color is the wild-type phenotype, while the white eye color is a result of a mutation in the gene responsible for eye pigment production. These eye color variations are commonly used in genetic studies to understand inheritance patterns and gene function.
Are sepia eyes a recessive trait in drosophila?
Yes, sepia eyes in Drosophila are a recessive trait. The sepia eye color phenotype is caused by a mutation in the gene that encodes the enzyme dopachrome isomerase, resulting in the brown eye color characteristic. Two copies of the mutated gene are required to exhibit the sepia eye color phenotype.
What is the conclusion of mutagenic effect of vodka on the phenotype of fruit fly?
some mutations include the change in eye color of the drosophila melanogaster
How did Morgan determine that red-eye color is Drosophila is an X-linked trait?
Morgan determined that red-eye color in Drosophila is an X-linked trait by conducting a series of genetic crosses. He observed that when he crossed white-eyed males (mutants) with red-eyed females (wild type), all the F1 offspring had red eyes. When he then crossed F1 males with F1 females, he found a 3:1 ratio of red-eyed to white-eyed flies among the males, indicating that the trait was linked to the X chromosome. This inheritance pattern suggested that the white-eye mutation was recessive and located on the X chromosome, confirming its X-linked nature.
Why is the color of the eye different from the color around the eye?
The color of the eye is determined by the amount and type of pigments in the iris of the eye.
Where did the eye get its color?
Eye color is based on the amount and type of pigments in the iris of the eye.
Do you get eye color from pigments?
Yes. Eye color is caused by the amount and type of pigment in the iris of the eye.
How do eyes get there color?
Eye color is based on the amount and type of pigments in the iris of the eye.
How did Morgan determine that eye color in drosophila is an x linked trait?
He crossed them. Some males... some females... Males have only one X chromosome so if it's carried in it then,...
What gives color to the eye?
Melanin. The amount and type of pigment in the iris of the eye gives the eye it's color.
