Detailed explanation-1: -For example, sexual reproduction allows for variation, but gestation usually takes a long time and it requires heavy parental input. Asexual reproduction occurs quickly, but because all of the offspring have the same genetic information, individuals are more susceptible to disease.

Detailed explanation-2: -Syngamy refers to the fusion of haploid sex cells resulting in the formation of a diploid zygote. Thus, in essence, syngamy refers to fertilization. It is the most common type of reproduction in multicellular sexual populations, including humans.

Detailed explanation-3: -Some of the disadvantages of sexual reproduction include the fact that it is generally slower, more energy costly, and more time consuming. Although some sexually reproducing organisms can produce vast numbers of offspring, asexual reproduction typically produces far more offspring at a faster rate.

Detailed explanation-4: -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.
