What if in the above cross 100 males were produced and 200 females how many total red eyed flies would there be?
If 100 out of the 300 flies are males, and all males have red eyes, then 100 red-eyed male flies would be produced. If 50% of the 200 female flies have red eyes, then 100 red-eyed female flies would also be produced. Therefore, there would be a total of 200 red-eyed flies: 100 males and 100 females.
In fruit flies straight wings are dominant and curly wings are recessive. What will the generations look like?
If we cross a homozygous dominant fruit fly with straight wings (WW) and a homozygous recessive fruit fly with curly wings (ww), all offspring in the first generation (F1) will be heterozygous (Ww) and exhibit straight wings. If we then cross two F1 flies (Ww x Ww), the second generation (F2) will show a phenotypic ratio of 3 straight-winged flies to 1 curly-winged fly, resulting in about 75% straight wings and 25% curly wings.
When doing a genetic cross why is it necessary to remove the parent flies before the pupae have hatched?
Usually, the parent flies will have a different genotype to the F1 generation (their offspring). For example, if the parents had WW (black eyes) and ww (white eyes), their offspring would all have Ww (black eyes). If you were experimenting further, you would want the F1 generation to cross - with Ww X Ww. If you did not remove the parental generation, you could have crosses between them and the F1 generation, which would result in different genotypes. If the parents were not removed, you could have the following crosses: Ww X WW Ww X ww WW X ww Ww X Ww The only cross that you would desire in the experiment would be F1 X F1 (Ww X Ww), which would give you the desired genotypes for the F2 generation.

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 is the importance of comparing wild type and mutant fruit flies in genetic research?
Comparing wild type and mutant fruit flies allows researchers to identify genes responsible for different traits. Mutant fruit flies with altered traits provide insights into gene function and pathways. This comparison helps in understanding genetic mechanisms and their roles in development, behavior, and diseases.
How do you kill thunder flies?
The only way to try and kill thunder flies is by using an insecticide. You should look for an insecticide that is designed to kill thrips and it should get rid of the thunder flies as well.
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.
How should a paper on allusions in 'Lord of the Flies' be written?
it should be written in English
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
