When genes are on the same chromosome but very far apart, they assort independently due to crossing over (homologous recombination). This is a process that happens at the very beginning of meiosis, in which homologous chromosomes randomly exchange matching fragments. … In this case, the genes are linked.
Why are genes linked?
Linked genes are genes that are likely to be inherited together because they are physically close to one another on the same chromosome. During meiosis, chromosomes are recombined, resulting in gene swaps between homologous chromosomes. … It is impossible for linked genes to be on different chromosomes.
How do you know if two genes are linked?
If the genes are far apart on a chromosome, or on different chromosomes, the recombination frequency is 50%. 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.
