Key Idea 4:
The continuity of life is sustained through reproduction and development.
Species transcend individual life spans through reproduction. Asexual reproduction produces genetically identical
offspring. Sexual reproduction produces offspring that have a combination of genes inherited from each parent’s
specialized sex cells (gametes). The processes of gamete production, fertilization, and development follow an
orderly sequence of events. Zygotes contain all the information necessary for growth, development, and eventual
reproduction of the organism. Development is a highly regulated process involving mitosis and differentiation.
Reproduction and development are subject to environmental impact. Human development, birth, and aging should
be viewed as a predictable pattern of events. Reproductive technology has medical, agricultural, and ecological
