When a gene is duplicated resulting in two copies, there are three possible fates for the duplicate copy Sort each item to the appropriate bin. Potential to generate a new phenotype Most likely outcome for duplicated genes Pseudogene (Nonfunctionalization) 4 Both gene copies are required to carry out the functions of the original gene One gene copy is inactivated due to deleterious mutations Subfunctionalization Most interesting evolutionary outcome for duplicated genes Least likely outcome for duplicated genes Reset Help Neofunctionalization

Why is it easier to identify spontaneous mutations in bacteria than in most eukaryotes?     The mutations occur at a much higher frequency.     Because bacteria have smaller genomes.     The mutations can be induced via exposure to the bacteriophage.     The mutations are expressed directly in descendant cells because bacteria are haploid.     The mutations are visible as color changes within a bacterial colony.

. A sudden, novel genetic change which can be stably inherited (as in the case of red flower color appearing suddenly in the normal yellow-flowering evening primrose) is the accepted definition of: DNA damage (as proposed by Hugo de Vries) non-homologous recombination (as proposed by Hugo de Vries) transposition (as proposed by Hugo de Vries) homologous recombination (as proposed by Hugo de Vries) mutation (as proposed by Hugo de Vries)

The loss of genes that occurred as the horse nematode (Ascaris megalocephala) evolved into a specialized parasite, with only 6 chromosomes in each diploid cell, was most likely due to: deletion of one or more chromosomes deletion of the entire genome duplication of the entire genome duplication of one gene duplication of one chromosome
