Why are linked genes often inherited together?
Understand the Problem
The question is asking about the concept of linked genes and their inheritance patterns. It is seeking to understand why certain genes are often passed down together from one generation to the next.
Answer
Linked genes are inherited together because they are located close to each other on the same chromosome.
Linked genes are often inherited together because they are located close to each other on the same chromosome. This proximity reduces the likelihood of them being separated during meiosis by genetic recombination.
Answer for screen readers
Linked genes are often inherited together because they are located close to each other on the same chromosome. This proximity reduces the likelihood of them being separated during meiosis by genetic recombination.
More Information
Genetic recombination can sometimes separate linked genes if crossing over occurs between them, but this is less likely the closer the genes are to each other.
Tips
A common mistake is assuming that all genes on the same chromosome are always inherited together; recombination can still separate them, especially if they are far apart on the chromosome.
