What are inherited traits of fruit flies?
eye color (red/white) and body color (brown/yellow). In fruit flies, eye color is a sex-linked trait determined by a single gene with two alleles. Red color is dominant to white eye color. Body color is an autosomal trait determined by a single gene with two alleles, where brown is dominant to yellow. -Angela B.
Two fruit flies having the same red eye color is an example of two organisms that are heterozygous or homozygous?
Two fruit flies having the same red eye color is an example of two organisms that are homozygous for the eye color trait. If the fruit flies had different eye colors, then they would be heterozygous for the trait.
What are the 5 traits commonly used when studying genetics when using fruit flies?
eye color, body shape, eye shape, wing shape
Which Chromosome has the trait For Blue Eyes?
Chromosome 19 has a blue/green gene. Chromosome 15 has a brown/blue gene. The genetics of eye color are more complex than realized previously, and more than one gene is involved in determining eye color.
How do you explain the principle of dominance?
Genetic dominance? One gene is dominant over the other gene in the chromosome pair by having it protein product made totally at the expense of the recessive gene, or the protein product dominates production. For instance, blue eye color is recessive to brown eye color. You have two alleles ( different molecular form of the same gene ) in this case; one from one parent and one from the other parent. Only the brown allele expresses and is called dominant then.

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.
Do you get your eye color from your parent?
Yes you get your eye color from your parent. The parent that carries one dominant gene and one recessive gene for a specific eye color and the other parent carries two recessive genes for a different eye color, you will get the eye color of the parent who carries the dominant and recessive gene. In other words, the dominant gene trumps the recessive gene. In another scenario, if both parents carry two recessive genes for a specific eye color, then you will inherit the recessive gene of that color.

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.

What are the genes that control eye color called?
Eye color is a polygenic phenotypic character.Eye color is determined by amount and type of pigment in eye's iris.eye color is determined by multiple genes.EYCL1 eye color- green/blue. Gene located on chromosome 19EYCL2 eye color- brown eye colorELCL3 eye color- brown/blue. Gene located on chromosome15.
How many genes influence the color and the eye of a tiger?
A single gene influences the color and the eye (color) of a tiger. In other words One gene. Source: Life Science book
What gene causes one to have brown eyes?
It is not just one gene that causes the color of eyes. Eye color genetics is complicated and it takes many genes to create an eye color. Regardless of the parents' and children's eye color any combination can occur even for the same eye color.
What protein does the eye color gene encode?
melanin
Why do some fruit flies have white eyes?
Due to genetic mutation. Flies' genes can mutate into a form that prevents any pigment from getting into the eyes. When a fly receives two genes called "recessive genes" from it's parents that cause the fly from putting color into it's eyes then they appear white. If they only have one gene that tells them to have white eyes then the more "dominant gene" will prevail and cause them to have another color eye such as red.
