How is the way hox genes are expressed in mice different to the way they are expressed in fruit flies?
Hox genes in mice and fruit flies are expressed similarly in that the genes themselves are similar enough to trade places and still function. The genes are expressed different because although you can switch the genes around, the outcome will result in the improper physical characteristic.
What else can I help you with?
In fruit flies eye color is determined by?
Eye color in fruit flies is determined by the combination of genes they inherit, specifically genes located on the X chromosome. Mutations in these genes can lead to changes in eye color, with different alleles causing variations in pigmentation. The interaction of these genes ultimately determines the specific eye color of a fruit fly.
What does the genes in fruit flies indicate about their evolution?
The genes in fruit flies can provide insights into their evolutionary history, including how they have adapted to different environments over time. By studying the genetic markers in fruit flies, researchers can track how mutations have occurred and spread throughout populations, helping to understand the mechanisms driving their evolution. This information can also shed light on the relationships between different species and how they have diverged from a common ancestor.
Why was Thomas Hunt Morgan important with fruit flies?
Thomas Hunt Morgan was important with fruit flies because he used them to establish the chromosome theory of inheritance, demonstrating that genes are located on chromosomes. His research with fruit flies provided key insights into how genes are inherited and laid the foundation for modern genetics.
Why can the genetics of fruit flies be applied to humans?
Fruit flies share many genes with humans and have a short life cycle, making them ideal for genetic research. Studying fruit fly genetics can provide insights into basic biological processes that are conserved across species, helping us understand human genetics and diseases better. By manipulating fruit fly genes, researchers can discover new genes associated with human diseases and potential drug targets.
What are the key differences between cis and trans genes in terms of their regulation and expression?
Cis genes are regulated and expressed on the same chromosome they are located on, while trans genes are regulated and expressed on a different chromosome. This difference in regulation can impact how genes interact with each other and influence their expression levels.

How is the way hox genes are expressed in mice similar to the way they are expressed in fruit flieshow?
They reproduce quickly.

How many genes do fruit flies have on their chromosomes?
74
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
Why was Thomas Hunt Morgan important with fruit flies?
Thomas Hunt Morgan was important with fruit flies because he used them to establish the chromosome theory of inheritance, demonstrating that genes are located on chromosomes. His research with fruit flies provided key insights into how genes are inherited and laid the foundation for modern genetics.
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 trait is expressed when two different genes for the same trait are present?
dominant
Why might a geneticist use fruit flies to study how genes function?
Fruit flies have a short generation time, produce numerous offspring, and share many genes with humans. This makes them ideal for genetic studies that aim to understand how genes function and interact. Additionally, fruit flies are easy and inexpensive to maintain in a laboratory setting.

What is a trait that is not expressed when an organism receives genes for 2 different forms of a trait?
A trait that is not expressed when another is present is referred to as a recessive trait.
What are the key differences between cis and trans genes in terms of their regulation and expression?
Cis genes are regulated and expressed on the same chromosome they are located on, while trans genes are regulated and expressed on a different chromosome. This difference in regulation can impact how genes interact with each other and influence their expression levels.
