Sexual Reproduction & Its Characteristics - Practice Questions & MCQ

• Sexual reproduction involves the formation of the male and female gametes, either by the same individual or by different individuals of the opposite sex. 
• These gametes fuse to form the zygote which develops to form the new organism. 
• It is an elaborate, complex and slow process as compared to asexual reproduction.
• Because of the fusion of male and female gametes, sexual reproduction results in offspring that are not identical to the parents or amongst themselves.
• It involves the following stages:
  • Formation of haploid sex cells called gametes called gametogenesis
  • A fusion of the two gametes during fertilization
  • Mitotic divisions in the zygote to form embryo called embryogenesis
  • Growth and development of the embryo

Characteristics of Sexual Reproduction:

• It is biparental.
• Gametes are always formed.
• Fertilization takes place.
• It involves both mitosis and meiosis.
