Linked Genes Break Mendel's Principle of Independent Assortment

Independent assortment says alleles of different genes segregate independently during gamete formation.
This holds only for genes on different chromosomes or far apart on the same chromosome.
Linked genes, sitting close together, do not assort independently because they tend to stay together during meiosis.

Physical Linkage Keeps Alleles Together

Linked genes are on the same chromosome, so they travel into the same gamete together.
