Chapter 51, Problem 3TY
Summary Introduction
Introduction: Reproduction is an important phenomenon for ensuring the survival of species. The two different modes of reproduction are sexual reproduction and asexual reproduction. The asexual reproduction involves the production of offspring with genes inherited from a single parent. Whereas, the sexual reproduction involves the fusion of two haploid gametes to form a diploid zygote. One of the two gametes comes from male and the other gamete comes from female
