Chapter 6, Problem 11MC
Summary Introduction
Introduction:
Regardless of the species, the defining feature is always the same between the two sexes. The female sex produces the larger gamete, and the male produce the smaller, more motile gamete. Because all gametes in animals are produced through meiosis, it is a slight variation in how meiosis works in males and females that leads to this difference.
