What happens when there is a mutation in Hox genes in Drosophila?
Understand the Problem
The question is asking about the effects of mutations in Hox genes specifically in Drosophila, which are a model organism in genetic studies. It is looking for the biological consequences of such mutations, particularly how they might alter the body's structure or development.
Answer
Mutations in Hox genes in Drosophila cause dramatic changes like extra wings or legs for antennae.
When there is a mutation in Hox genes in Drosophila, there can be homeotic transformations, meaning one body part develops into another, such as extra wings or legs growing in place of antennae.
Answer for screen readers
When there is a mutation in Hox genes in Drosophila, there can be homeotic transformations, meaning one body part develops into another, such as extra wings or legs growing in place of antennae.
More Information
Hox genes hold crucial roles in defining the body layout during development, dictating the identity of each segment. Mutations in these genes can result in one body segment adopting characteristics of another, showing the modular and interchangeable nature of body part identity.
Tips
Misidentifying the functions of Hox genes or confusing them with other developmental genes can occur. Understanding their specific role in segment identity is crucial.
