Verified step by step guidance

Understand the concept of genetic linkage: Genetic linkage refers to the tendency of genes that are located close to each other on the same chromosome to be inherited together during meiosis.
Recall that genes located on different chromosomes assort independently according to Mendel's law of independent assortment. This means they are not linked.
Linked genes are not necessarily dominant or recessive pairs; linkage is about their physical proximity on a chromosome, not their dominance or recessiveness.
Linkage is stronger when genes are closer together on the same chromosome because there is a lower chance of recombination occurring between them during meiosis.
Therefore, the true statement regarding genetic linkage is that linked genes are located close together on the same chromosome and tend to be inherited together.
