Some species have lost the ability to cross over and in other species, like humans, have lost the ability in certain chromosomes. What factors do you think could reduc ...

Mutations in somatic (body)cells are generally not harmful as the altered gene may not have been active in that particular cell. However, a mutation that causes a chang ...
