What are linked genes?
Similarly, you may ask, what are linked genes give an example?
Linked genes are genes that are located on the same chromosome. Hence they are passed down together, and their phenotypes are often found together. An example of this would be the genes for red hair and freckles, which you usually see together in people.
Secondly, how do you know if genes are linked? In this case, inheritance of alleles at the two loci are independent. If the recombination frequency is less than 50% we say the two loci are linked. Under most models of meiosis, recombination frequencies cannot be larger than 50%. You can tell if the genes are linked by looking at the offspring.
Likewise, how are linked genes inherited?
When genes are close together on the same chromosome, they are said to be linked. That means the alleles, or gene versions, already together on one chromosome will be inherited as a unit more frequently than not.
What happens when two genes are linked?
When two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.
