Solution

The correct option is D linkage; recombination
Linkage is physical association of genes on the chromosome and these genes are called linked genes. Linked genes have a tendency to get inherited together.
The linked genes can be separated during crossing over and this results in non parental gene combinations. The term used by Morgan to refer the non parental gene combinations is recombination.
