Document Summary
Exam 1 (chapters 1-6, 50 multiple choice questions) Influence of heredity and environment in shaping development has been debated over centuries. Physical development follows same pattern in identical twins. About 40% of person"s personality traits are genetically inherited. John locke (1632-1704) stated that children enter life with clean slate . In reality, both heredity and environment influence development. Babies with severe hearing loss are wired to coo and babble in first few months, but will not utter first word. With fertilization, single cell, called zygote, is formed. Sperm and ovum contain 23 pairs of chromosomes or genetic information. Test question: if you have a pair of twins (boy and girl), are they dizygotic or monozygotic. In 1866, john langdon down made first medical observations of genetic disorder called down syndrome. Cause is extra chromosome in 21st pair (trisomy 21) Characteristics include intellectual disabilities and delays in adaptive behaviors (communicating, socializing, etc. )
