He crossed them. Some males... some females... Males have only one X chromosome so if it's carried in it then,...

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.
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.
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.
Is color blind dominant or recessive?
recessive
Why are fruit flies an ideal organism for genetics research?
Drosophila(fruit flies) can produce plenty of offspring and have specific traits, such as eye color and body color/shape. They are easy to observe and therefore easily traced throughout the following generations.

A wild type Drosophila fly has long wings gray body and what color eyes?
Red... I think
Why did Morgan choose fruit flies for his experiment?
Morgan chose fruit flies (Drosophila melanogaster) for his experiment because they have a short life cycle, produce many offspring, and have easily observable traits like eye color that follow simple patterns of inheritance. These characteristics made fruit flies a good model organism for studying genetics and understanding the principles of heredity.
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 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.
What is Joseph Morgan's favourie color?
There is no public information available on actor Joseph Morgan's favorite color.
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
Is human eye color a sex linked character?
No, human eye color is not a sex-linked trait. It is determined by multiple genes and is inherited in a complex manner involving both genetic and environmental factors.
Why is the color black linked to evil?
Because it's believed to be the devil's color of darkness. This theory is wrong because god made all colors. The color black is really supposed to be linked to beauty, and it IS a beautiful color.
Does color determine sex of a duck?
No the color of the duck does not determine the sex of the duck.
