How many cells does a fly and a mouse have?
A fly typically has around 100,000 cells, while a mouse has around 75-100 trillion cells.
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.

What is the genotype of a red-eyed male fruit fly?
Red eyes is a dominant sex-linked gene in the fruit fly. Males with red eyes have the genotype XRY, where R is for the red gene.
How long is the lifespan of the average housefly?
The average lifespan of a housefly is about 2.5 weeks.
LOTS! They can carry any germ from anything. They probably landed on mold, rotting food, dung, a corpse, and lots of other things! Eating a few flies can cause quite a bit of trouble to your body....
Do flies have the same organs as us?
Flies and humans have different organ systems based on their evolutionary adaptations. While flies have organs for feeding, digestion, circulation, and reproduction like humans, their anatomy is specialized for their unique ecological niche, which includes characteristics like compound eyes, specialized mouthparts for feeding, and simple respiratory systems.
What do you do if a fly goes in your ear?
If a fly goes in your ear, try to remain calm and tilt your head to the side to let gravity help the fly come out. Avoid using objects to try to remove it as this can push it deeper. If the fly doesn't come out on its own or you experience pain or other symptoms, seek medical assistance.
All offspring would have red eyes because the gene for red eyes is dominant over the gene for vermilion eyes. The offspring would all be heterozygous for eye color, inheriting one red-eyed allele from the female and one vermilion-eyed allele from the male.
Flies play a role in pollination by transferring pollen between plants. They also help in nutrient cycling by breaking down organic matter, such as dead animals and waste. Additionally, flies serve as a food source for various animals in the ecosystem.
What happens when a fly lands on a human?
I have seen it happen in person and actually I never noticed anything at all except they can be real good at avoiding a flyswatter. If you were looking for what is going on in the flys mind once it lands on a human science just has not gotten there yet! People have noticed a couple of flys do a little "hand Washing" gesture. While others seemed to enjoy the game of tormenting us or landing in our juice glasses. (not actually proven YET) Most other events that you may be thinking about are pure coincidence, like fly lands Grandpa dies spirit in the room stuff. I guess until science catches up with the activity of the fly we will continue to guess! Great question though!
What happens if a housefly goes into your ear?
go to the doc to have it removed with tweezers. IT WONT KILL YOU!
The above answer is probably good advice if by chance the fly got stuck in your ear, but this does not usually happen since flies are very skittish and would not normally be caught in this situation.
A fly enters a body cavity or open wound of other animals for the purpose of deposting eggs. It does this only when the animal is dead or very near death. Occassionally a fly might get confused and enter the ear or nostril of a living animal but it will soon correct its mistake before it gets swatted and it will not deposit eggs, a process which takes some time.
As for the dead and dying, the green bottle fly is the first to detect death (even just before it happens) and will enter any body orifice or wound and deposit its eggs. The resulting maggots are frequently used by forensic entymologists to determine the time of death.
So unless you are dead or dying, you have nothing to fear from a wayward housefly - unless,of course, you smell like you are dead or dying. Flies are incredibly attracted to things that smell like feces, urine, putricine and cadaverine, odors that can be present on a horribly unbathed body. Still they will not deposit eggs unless you are are dead.
They are part of nature. All creatures have their place in the ecosystem. Flies do some good things, like getting rid of waste material after larger creatures have eaten an animal and leave a carcass behind. Flies and other insects feed on the remains. Flies are themselves food for other creatures. Those creatures are in turn food for other creatures and do things that are part of nature. So flies are important, even if people don't like them.
Why do flies live for only 5 days?
The lifespan of flies is short due to their high reproductive rate and the presence of predators and environmental factors that limit their survival. Flies prioritize rapid reproduction over longevity to ensure the continuation of their species. Additionally, flies have a high metabolic rate, leading to faster aging and a shorter lifespan.
I don't think so, they do spread alot of diseases and they are so small they can't do anything but fly.
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.
What are the four stages in a fruit flies life?
The four stages in a fruit fly's life cycle are egg, larva, pupa, and adult. Fruit flies lay their eggs on decaying fruits and vegetables, which hatch into larvae (or maggots) that feed and grow before entering the pupal stage. The adult fruit fly emerges from the pupa and begins the cycle again by laying eggs.
The fly is in the class of animalia and in the sub-class insectia. An insect is just a more specific type of animal (a class), just like a mammal or a reptile. Living things are classified from large, broad groups into smaller and smaller groups. The largest of these that is important here is a kingdom. Kingdoms are broken up into phyla, which are smaller. Phyla are then broken up into classes, which are broken up into orders, which are broken up into families, etc. Fruit flies are classified into two families (Tephritidae and Drosophilidae) which are parts of the order Diptera (which includes all flies). Diptera is part of the class Insecta (which includes all insects). Insecta is part of the phylum Arthropoda (which include insects, arachnids, and crustaceans). And Arthropoda is part of the kingdom Animalia, or the animal kingdom. If you are looking for the "common fruit fly" its scientific name is Drosophila melanogaster.
How many babies can a fruit fly have in 2 weeks?
A female fruit fly can lay hundreds of eggs in her two-week lifespan. Each egg hatches into a larva, goes through metamorphosis, and emerges as a mature fruit fly ready to reproduce. This rapid reproductive cycle contributes to fruit flies' ability to quickly populate an area.
What is the purpose of the fruit fly lab?
The purpose of the fruit fly lab is to study genetics and inheritance patterns in Drosophila melanogaster, commonly known as fruit flies. These insects have a short lifecycle, making them ideal for genetic studies. By observing traits passed down through generations, scientists can better understand how genes work and are inherited.
What is the lifespan for the common housefly?
The common housefly typically lives for about 15 to 25 days. However, under ideal conditions, they can live for up to a month.
How many pairs of homologous chromosomes are in a fruit fly somatic cell?
5 homologous chromosomes are in a fruit fly somatic cells.
A fly grows through a process called metamorphosis. It begins as an egg, hatches into a larva (maggot), then develops into a pupa before finally emerging as an adult fly. This transformation allows the fly to grow and develop into its mature form.
What determines which end of a developing fruit fly becomes the head?
The distribution of maternal signaling molecules (such as bicoid and nanos) deposited in the egg during oogenesis determines the anterior-posterior axis in a developing fruit fly embryo. These molecules help to establish concentration gradients that guide the formation of head and tail structures.
In this case, the genotype of the white-eyed male fruit fly would be XwY, and the genotype of the heterozygous red-eyed female fruit fly would be XRXw. The expected ratio of genotypes in the offspring would be 1:1 for XRY (red-eyed males) and XRXw (red-eyed females).
What kind of symmetry do flies have?
Flies are arthropods and all arthropods have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
