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.

What should fruit flies should i cross to get mutant fruit flies other than the white-eyed?
You can cross fruit flies with different mutations, such as curly wings or ebony body color, to produce various mutant combinations. By crossing flies with different mutations, you can generate new mutant combinations and study their effects on traits and behaviors.
How many flies are produced each summer?
The number of flies produced each summer can vary widely depending on environmental conditions, species, and food availability. For example, a single female housefly can lay up to 500 eggs in her lifetime, leading to thousands of offspring in ideal conditions. In urban areas, it's estimated that millions of flies can be produced during the summer months. However, exact numbers are difficult to quantify due to the vast diversity of fly species and their varying reproductive rates.
Why are all white eyed flies males?
All white-eyed flies are males due to a genetic mutation linked to the X chromosome. In Drosophila melanogaster, the white eye color trait is caused by a recessive allele located on the X chromosome. Since males have only one X chromosome (XY), any mutation on that chromosome will manifest, resulting in white eyes. In contrast, females have two X chromosomes (XX) and would require two copies of the recessive allele to exhibit white eyes, making it rare for females to show this trait.
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.
What is the kingdom phylum class order family genus and species for the flies?
'Flies' are an Order of insects containing roughly a quarter of a million different species. Kingdom: Animalia, Phylum: Arthropoda, Class: Insecta, Order: Diptera. Any species belonging to the above, is a 'fly'.
What cross could Morgan had performed to make the first white eyed female fruit flies?
In order to produce flies with white eyes, they must have two recessive traits. These could have been produced by mating two heterozygous individuals for red eye color.
Do horse flies suck blood?
The females do. The males live on honeydew, nectar and sap.
Does a canary flies high?
Yes they do if they are males. Females chirp but don't sing
What does it mean when eagle flies above at a graveside funeral?
No I can not
What is the difference between a plane and spacecraft?
An aircraft flies in the Earths atmosphere, whereas a spaceship flies above the atmosphere.
What should fruit flies should i cross to get mutant fruit flies other than the white-eyed?
You can cross fruit flies with different mutations, such as curly wings or ebony body color, to produce various mutant combinations. By crossing flies with different mutations, you can generate new mutant combinations and study their effects on traits and behaviors.
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.
What type of chromosomes are found in fruit flies?
Fruit flies have three pairs of chromosomes, two autosomes and one pair of sex chromosomes (XX in females and XY in males).
What was the result when Morgan mated fruit flies with the genotypes X R X r and X R Y?
When Thomas Hunt Morgan mated fruit flies with the genotypes X^R X^r (female) and X^R Y (male), the offspring produced included both males and females. The expected genotypes of the offspring would be X^R X^R (homozygous red-eyed females), X^R X^r (heterozygous red-eyed females), and X^R Y (red-eyed males). All offspring would exhibit the red eye phenotype, as the red eye allele (X^R) is dominant over the white eye allele (X^r). Thus, the results demonstrate the inheritance patterns of sex-linked traits in fruit flies.
Are there sand flies in South Carolina?
Yes, there are sand flies in South Carolina. They are especially a nuisance along the coast. The females require a blood meal so the eggs can mature (males do not bite). Females lay eggs in mud, sand, and debris around the edges of ponds, springs, lakes, creeks, and in tree holes or on slime-covered bark.
What temperature do flies stop coming around?
Flies cannot survive at temperatures above 150 degrees Fahrenheit. Most flies will die at temperatures at or below 40 degrees Fahrenheit.
What are some other exercises that work similar muscles as the bench press?
You can try * Dumbbell press * Dumbbell flies * Pec dec flies * Cable cross overs * Push ups * Parallel Bar dips All the above exercises work out the chest or the pectoral muscles. Note: Bench Press is the most basic or rather the best exercise for muscular development in the chest area.
