Genetic linkage leads to the production of a significantly greater than expected number of gametes containing chromosomes with

Parental combinations of alleles

Explanation:

Genetic linkage is the linkage between genes on the same chromosomes. Linked genes inherit together.

More is the distance between two genes then more is the recombination frequency, less is the distance more tightly they are linked and less the recombination frequency.

In linked genes, parental combination (non-recombinant) of alleles are more common as compared to recombinant combination of alleles.
