Presentation transcript:

 Chromosomes  Autosomes  Sex Chromosomes  Deoxyribonucleic acid (DNA)

 Genotypes/Phenotypes  Alleles › Heterozygous/homozygous › Dominant/recessive › Incomplete dominance

 Genetic Disorders › Inherited Disorders  Phenylketonuria (PKU)  Huntington’s Disease › Abnormal Chromosomes

 Behavioral Genetics › Polygenic Inheritance › Monozygotic/Dizygotic twins  From Genes to Behavior › Reaction Range › Heredity and environment interact dynamically › Genes influence the environment › Environment makes children in a family different

 Zygote › Weeks 1-2  Implantation  Germ Disc  Placenta

 Embryo › Weeks 3-8 › Ectoderm/mesoderm/endoderm › Amnion/Amniotic Fluid › Umbilical Cord › Cephalocaudal Principle › Proximodistal Principle

 Fetus › Weeks 9-38 › Cerebral Cortex › Age of Viability

 General Risk Factors › Nutrition › Stress › Mother’s Age

 Teratogens › Drugs › Diseases › Environmental Hazards

 Teratogens Influence Prenatal Development › Depends on the genotype › Changes over the course of prenatal development › Affects a specific aspect of prenatal development › Depends on the dose › Damage may appear later

 Genetic Counseling  Prenatal Diagnosis  Fetal Medicine

 Stages of Labor › Stage 1 › Stage 2 › Stage 3

 Natural  Birth clinic  Home births

 Adjustments!  Post partum Depression  Post partum Psychosis

 Hypoxia  Cesarean Section  Premature Birth  Low/very low/extremely low birth weight  Infant mortality rates

 Physical, Perceptual, and Motor Development

 Newborn Reflexes  Assessment of the Newborn  Newborn’s States › Crying › Sleeping

 Heredity and Environmental Contributions  Stability of Temperament

 Growth of the Body › Nutrition/Malnutrition  Nervous System › Emerging brain structures › Structure and Function › Brain Plasticity

 Locomotion › Posture and Balance › Stepping › Perception › Coordination › Beyond Walking

 Fine Motor Skills › Reaching and Grasping › Handedness

 Smell  Taste  Touch  Hearing  Seeing › Color › Depth › Perceiving Objects
