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?
Male reproduction system
Is phenotype the way an organism looks and behaves a result of its genotype?
Yes. the phenotype is the visible manifestation of a genotype. In the example of fruit flies, if red eyes are dominant and white eyes recessive, than the genotypes "AA" and "Aa" will give a dominant phenotype of red eyes. Conversely, a recessive "aa" will give a phenotype of white eyes.
If Apple maggot flies appear to be two separate races what makes these races different?
They have different allele frequencies.
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.
In fruit flies gray body color is dominant over black body color. Suppose two fruit flies heterozygous for the alleles that carry body color are crossed and 200 offspring are produced. How many would?
100 Black Bodies.

In fruit flies gray body color is dominant over black body color?
The statement, "In fruit flies, gray body color is dominant over black body color" is true. The allele for gray body color is dominant.

Can the genotype for a gray-bodied fly be determined Why or why not Describe all of the possible genotypes for a fly with that phenotype?
Assuming that we are talking about fruit flies, then you should be able to determine this. Gray bodied flies would be the dominant and ebony bodied flies would be recessive. So, the results can only be a homozygous dominant fly (GG) or heterozygous fly (Gg). If you cross that fly with a ebony bodied fly (gg) and there is a result of some ebony bodied flies, then you know the original fly was heterozygous. If you result in all gray flies, then it was dominant.Source(s):Biology 101
Are red compound eyes dominant in flies?
Yes.

Is apterous wings dominant in fruit flies?
No. The apterious gene is recessive.
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 is the conch linked with in Lord of the Flies?
It represents authority.
If Apple maggot flies appear to be two separate races what makes these races different?
They have different allele frequencies.
What could you do to determine the genotypes of two gray bodies flies?
You could cross breed them and depending on what their offspring is, you can determine what their genotype is.
