What are the sexes and eye colors of flies with the following genotype?
White eyes are recessive sex-linked genes in fruit flies. White eyed males fruit flies have XWY, where W is for white eyes.
What should fruit flies should i cross to get mutant fruit flies other than the white-eyed?
You can cross fruit flies with different mutations, such as curly wings or ebony body color, to produce various mutant combinations. By crossing flies with different mutations, you can generate new mutant combinations and study their effects on traits and behaviors.
If a heterozygous red eyed female fruit fly mates with a heterozygous red eyed male fruit fly the ratio of the resulting offspring that will have red eyes is while the remaining r?
The resulting offspring from this cross will have a phenotypic ratio of 3 red-eyed : 1 white-eyed. This is based on the typical 3:1 phenotypic ratio observed when two heterozygous individuals are crossed for a single gene trait like eye color in fruit flies.
If you had a red eyed fruit fly but didnt know whether or not it was a carrier for white eyes how could you find out?
In fruit flies white eyes are an X-linked trait (found on the X sex chromosome). Like humans, the females have two X chromosomes and the males have one X chromosome and one Y chromosome.Determine the sex of the fly:If the fly in question is a male then it cannot be a carrier. If it is a female then it could be a carrier since white eyes are a recessive trait. (Males are said to be hemizygous since they do not have matching sex chromosomes.)Preform a cross test:To see if a female is a carrier for white eyes (heterozygous for the trait) mate her with a red-eyed male. If she is heterozygous, then all the female offspring should have red eyes (half are carriers for white eyes). Half of the male offspring should have white eyes and the other half should have red eyes. The males get one X chromosome from the mother and one Y chromosome from the father so any expression of red or white eye color comes from the mother; the presence of white-eyed male offspring proves that the mother is a carrier (heterozygous).If she is homozygous for red eyes then 100% her offspring will have red-eyes in the test cross.
How many unit eyes does a fruit fly have?
A fruit fly, also known as Drosophila Melanogaster, has two compound eyes that are each made up of 800 unit eyes. These unit eyes are called ommatidia. Each ommatidium (sing.) contains eight photoreceptors labeled R1-R8.
What are the sexes and eye colors of flies with the following genotype?
White eyes are recessive sex-linked genes in fruit flies. White eyed males fruit flies have XWY, where W is for white eyes.
How do fruit flies see?
With their eyes.
Why do fruit flies have white eyes?
they dont well actually some fruit flies do. it depends on if they are a mutant type of fruit fly or not. there are also flies that have messed up wings, these types of flies are called vestigial. there are also fruit flies that don't even have eyes. all of these types of fruit flies are mutants and are used for testing.
What color eyes does blind fruit flies have?
red
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 significance of the sepia eyes trait in the Drosophila genotype and how does it impact the overall characteristics of the organism?
The sepia eyes trait in the Drosophila genotype is significant because it affects the color of the fly's eyes, giving them a brownish hue instead of the typical red. This trait is caused by a mutation in a specific gene that controls eye pigmentation. The sepia eyes trait does not have a major impact on the overall characteristics or behavior of the organism, as it is primarily a cosmetic difference.
What was the result when Morgan mated a white fruit fly with a red eyed female fruit fly?
When Morgan mated a white-eyed male fruit fly with a red-eyed female fruit fly, the first generation offspring all had red eyes. In the next generation, because females would have the X chromosome for white eyes, about half the offspring would have white eyes. The offspring with white eyes were all male, meaning he discovered eye color in fruit flies showed a sex-linked trait. The result of this was a generation of red eyed and white eyed individuals. If the red eyed female was heterozygous, this is possible.
What was the result when Morgan mates a white eyed male fruit with a red eyed female fruit fly?
When Morgan mated a white-eyed male fruit fly with a red-eyed female fruit fly, the first generation offspring all had red eyes. In the next generation, because females would have the X chromosome for white eyes, about half the offspring would have white eyes. The offspring with white eyes were all male, meaning he discovered eye color in fruit flies showed a sex-linked trait. The result of this was a generation of red eyed and white eyed individuals. If the red eyed female was heterozygous, this is possible.

What are some characteristics of the Drosophila Melanogaster?
Drosophila melanogaster is a small fly that is often found near fruit. They are often know as fruit or vinegar flies. The flies have red eyes and are a yellowish color.
