Info

Introduction Stages of an Organism’s Life Cycle: Development: All changes that occur from a fertilized egg or an initial cell to an adult organism. Reproduction: Production of offspring that carry genetic information in the form of DNA, from their parents. Two types of reproduction: 1. Sexual Reproduction 2. Asexual Reproduction
Types of reproduction: 1. Sexual Reproduction: Most common type of animal reproduction. Male and female gametes or sex cells (sperm and egg cell) join together to create a fertilized egg or zygote. The offspring has genetic information from both parents. Offspring are genetically different from each parents and their siblings. Advantages: Ensures genetic diversity of offspring. • Population more likely to survive changing environment. Disadvantages: Cannot reproduce without a partner of opposite sex. Considerable time, energy, and resources spent to find a suitable mate. Parents only pass on 1/2 (50%) of their genetic information to each offspring.
