5 Explain why there were no white eyed female fruit flies?
The gene for eye color is only carried on the X chromosome. Since females have two X chromosomes and white is recessive, there are no white-eye females.
How many chromazones do fruit flys have?
They have 4 pairs ofchromosomes not chromazones. one sex chromosome and three autosomes.
What is the meaning of carcophagus?
Fruit eating
What was the result when Morgan mated a white eyed male fruit fly with a red eyed female fruited 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.
Do birds eat meat and fish and insects and fruit and seeds and nectar?
Some do, birds of prey such as eagles, falcons etc are carnivores meaning they eat meat. Other birds such as parrots are herbivores meaning they eat seeds, fruit etc
Where is the gene for fruit flies eye color?
The gene for fruit fly eye color is located on the X chromosome. It codes for a protein called "eye color," which determines the pigmentation in the eyes of the fruit fly. Mutations in this gene can lead to different eye colors in fruit flies.
WHO concluded that the gene for eye color is located on the sex chromosome?
It was Thomas Hunt Morgan who concluded that the gene for eye color is located on the sex chromosome through his work with fruit flies in the early 20th century.
Which genotype represents a white-eyed male fruit fly?
The genotype for a white-eyed male fruit fly is X^wY, where X^w represents the white eye color allele on the X chromosome and Y represents the Y chromosome. In fruit flies, eye color is located on the X chromosome, so males only have one copy of the eye color gene.
In fruit flies eye color is determined by?
Eye color in fruit flies is determined by the combination of genes they inherit, specifically genes located on the X chromosome. Mutations in these genes can lead to changes in eye color, with different alleles causing variations in pigmentation. The interaction of these genes ultimately determines the specific eye color of a fruit fly.
Is sepia eyes sex linked in fruit flies?
Yes, sepia eyes in fruit flies is linked to the X chromosome and is a sex-linked trait. The gene responsible for sepia eye color is located on the X chromosome, which results in a different inheritance pattern compared to genes located on autosomes.
Which chromosome determines hair loss in fruit flies?

Are chrysanthemums a fruit or a flower?
It's a flower. Named from the Greek prefix "chrys-" meaning golden (its original color) and "-anthemion," meaning flower.
Short sex chromosome discovered in fruit flies?
The short sex chromosome in fruit flies, known as the Y chromosome, carries genes related to male traits and fertility. It determines the sex of the offspring when paired with an X chromosome. In evolutionary terms, the Y chromosome has undergone significant degeneration, leading to a size reduction and loss of genetic material compared to the X chromosome.
Is apterous wings sex-linked in fruit flies?
Yes, apterous wings in fruit flies are sex-linked, meaning the gene responsible for this trait is located on the sex chromosome (X or Y). In this case, apterous wings are usually associated with the X chromosome, making it more common in males (XY) than in females (XX) due to hemizygosity.
In fruit flies one genotype for red eyes is written XRXR. The R stands for the dominant allele for red eyes. What does the X stand for?
The "X" stands for the X chromosome. In fruit flies, the letter "X" is used to represent the sex chromosome that carries the gene controlling eye color. The genotype XRXR indicates that the individual has two copies of the X chromosome, with both carrying the dominant allele for red eyes.
Is the color called orange cause of the fruit?
Yes, the color was named after the fruit.
What genotype represents a white eyed male fruit fly?
The genotype for a white-eyed male fruit fly is X^wY, where X is the sex chromosome and Y is the Y chromosome. The w denotes the gene for white eyes located on the X chromosome. This genotype indicates that the male fruit fly has a white-eye phenotype due to the recessive white eye allele.
