How Is Sex Determined?

6. Describe, from fertilization, the major pathways of normal male sexual development; include the stages in which genetic sex, gonadal sex, and phenotypic sex are determined.

Summary Introduction

To determine: The major pathways of normal male sexual development from fertilization and include the stages in which genetic sex, gonadal sex, and phenotypic sex are determined.

Introduction: Humans reproduce by sexual reproduction. The fusion of male gametes and female gametes gives rise to a zygote. 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 the zygote is called fertilization.

Explanation of Solution

The male reproductive system includes components such as testes, epididymis, vas deferens, accessory glands, urethra, penis, and scrotum.

The major pathways of the development of the male reproductive system include:

  • Genetic sex

    Chromosomes of an individual are used to determine its genetic sex. A sperm with a Y chromosome, fertilizing an egg with X chromosome gives rise to a zygote having XY sex chromosomes. An individual having one X chromosome and one Y chromosome is referred to a male.

  • Gonadal sex

    The male gonads are called testes. The determination of gonads does not take place during conception...
