Adaptation model: Duplication creates redundancy One copy gains new beneficial f

Question

Adaptation model: Duplication creates redundancy One copy gains new beneficial function through mutation/s), then loses ancestral function Other copy preserves ancestral function Should we expect to see evidence of a selective sweep? O Neither copy should show evidence of a selective sweep inside the gene. O Both copies should show evidence of a selective sweep inside the gene. O The copy that acquired a new function should show evidence of a selective sweep inside the gene, but the other copy should not The copy that maintained the ancestral function should show evidence of a selective sweep inside the gene, but the other copy should not.

Explanation / Answer

Correct--- The copy that acquired new function should show evidence of selective sweep inside the gene, but the other copy should not.

Explanation

Selective sweep or Genetic hitchhiking is reduction of Variotion in the genotype of an organism by mutation. Selective sweep results from a beneficial allele which s fixed recently by means of positive Natural Selection.

We know in adaption one copy gets additional function i.e it becomes beneficial allele while the other copy maintains the parental ancestry. The copy with parental ancestry could be haramful or it may not favour the organism in a new envoronment.
