The Human Reproductive System

Discuss and compare the products of meiosis in human females and males. How many functional gametes are produced from the daughter cells in each sex?

Summary Introduction

To compare: The products of meiosis in human females and males.

Introduction: Humans reproduce by sexual reproduction. Gonads are the organs where the male and the female gametes are produced. The male gametes are produced with the help of male sex hormones called androgens and the female gametes are produced with the help of female sex hormones called estrogens. The process of production of zygote is referred to fertilization.

Explanation of Solution

The male reproductive system includes components such as testes, epididymis, vas deferens, accessory glands, urethra, penis, and scrotum. The female reproductive system includes components such as ovaries, oviducts, uterus, and vagina. Human males produce sperms as a product of meiosis and human females produce eggs as a product of meiosis.

Similarities between sperms and eggs are as follows:

  • Sperms, as well as eggs, are gametes which fuse to form a zygote.
  • chromosomes are present in both sperms as well as eggs.

Differences between sperms and eggs are as follows:
