Is this significance in Meiosis? Explain I. Enhances genetic variation II. Maintains ploidy in sexually reproducing organisms III. Allows for the potential repair of damaged DNA - ANSWER-I. Genetic variation is enhanced through the process of recombination and the separation of homologous chromosomes. II. Maintenance of ploidy in sexually reproducing organisms is achieved because gametes contain exactly half the number of chromosomes present in the mature organism. During fertilization, a ...
