Question

What do you call the movement of a gene (gene flow) from one species into the gene pool of another by the repeated backcrossing?

• A. Parental hybridization
• B. Interogressive hybrd.
• C. Back hybridization
• D. Stabilizing hybrd.

Answer 1

The correct option is B

Interogressive hybrd.

Introgression, also known as introgressive hybridization, in genetics (particularly plant genetics) is the movement of a gene (gene flow) from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species.
