Document Summary
Developmental psychology: study of the continuity and change across the lifespan of an individual. There are different stages of development in a human from the time they are conceived to the time they are born and delivered. The prenatal stage: ends with the birth of the individual and begins 9 months before when the human was conceived. Zygote: fertilized egg that contains both chromosomes from the mother and the father, from the egg and the sperm. Y chromosome used to fertilize: male; x chromosome used to fertilize: female. Male zygotes are more unlikely to complete the full journey of implanting than compared to female zygotes. Embryo: period that lasts from the second week until the eighth week; at this stage there is a beating heart and other body parts like arms and legs. The womb is an environment that has a powerful impact on the development of an infant.
