Chapter 12 Chromosomal Patterns of Inheritance
... All the genes on one chromosome form a linkage group, which is broken only when crossing-over occurs. Genes that are linked tend to go together into the same gamete. If crossing-over occurs, a two-trait cross involving dihybrids results in all possible phenotypes among the offspring, but the expecte ...
