Youreka Sciences describes the benefits and tradeoffs of both types of reproduction (sexual and asexual) and explains why many organisms favor sexual reproduction. Talk Overview: There are two types of reproduction: asexual and sexual reproduction. Though asexual reproduction is faster and more energy efficient, sexual reproduction better promotes genetic diversity through new combinations of alleles during meiosis and fertilization. However, as Youreka Sciences explains, both of these types of reproduction can be beneficial to different organisms.
