WebChromosomes can have different functions in various types of cells of the same organism. B One of the most likely explanations for the evolutionary origin of sexual reproduction is that (1 point) a. organisms could then move onto land. b. DNA replication errors could be corrected by recombination. c. more and larger offspring could be produced.
