Q. Bateson used the term coupling and repulsion for linkage and crossing over. Choice the correct coupling and repulsion combination [table] Coupling | Repulsion [/table]

A) [table] AABB, aabb | AAbb, aaBB [/table]
B) [table] AABB, aabb | AABB, AAbb [/table]
C) [table] AAbb, aaBB | AaBb, aabb [/table]
D) [table] aaBB, aabb | AABB, aabb [/table]
