• A.
  Crossing over
• B.
  Linkage
• C.
  Qualitative inheritance
• D.
  Gene interaction

Answer 1

The correct option is B

Linkage
Linkage
The phenomenon in which closely located genes get inherited together as a unit is called linkage. Tightly linked genes have less probability of separation.

Crossing over
Crossing over refers to the exchange of segments between the non-sister chromatids of homologous chromosomes.

Gene interaction
Gene interaction is the relationship between two genes in which the function and expression of one gene is influenced by the other.

Qualitative inheritance
Qualitative inheritance refers to the inheritance of a trait that gets expressed differently among individuals of a species.
