Genes on the same chromosome can be:

Distinguish between: Linkage and Recombination.

What is the arrangement of genes on chromosomes resulting from crossing over called?

Mendel observed that some traits do not assort independently. Later research showed that this is due to .....

Describe linkage and recombination in detail.

Genes $p, q,$ and $r$ are arranged on a chromosome. If the recombination frequency between $p$ and $q$ is $10 \%$,the recombination frequency between $q$ and $r$ is $20 \%$,and the recombination frequency between $p$ and $r$ is $10 \%$,what is the order of the genes on the chromosome?
