Question

Exon recombination has produced novel genes and, therefore, new proteins with new combinations of protein domains. The process of exon shuffling in the immunoglobulins has led to new combinations is due to ______________ followed by natural selection of advantageous the new genetic results of the shuffling.

occasional misalignment of homologous chromosomes followed by unequal crossing over and recombination within introns to give duplications or losses of exons

convergent evolution of new functions

divergent evolution of new functions

special repair enzymes that select for advantageous domain combinations

alternative allele expression
