Final answer:
Chromosomes are units of linked genes due to gene linkage on the same chromosome, leading to genes traveling together during gamete formation.
Explanation:
Chromosomes can be described as units of linked genes because genes are located on chromosomes, and when genes are on the same chromosome, they tend to travel together during gamete formation due to a phenomenon known as gene linkage. This physical connection on the same chromosome results in these genes being inherited together, impacting the inheritance patterns observed.
