Study Notes
Evolutionary Processes
- Natural selection favors individuals best suited for survival and reproduction.
- Paul Baltes posits that evolutionary selection benefits remain constant throughout life.
Genetic Foundations
- Genes serve as units of hereditary information, instructing cell reproduction and protein assembly.
- All human body cells, except sperm and egg, contain 23 paired chromosomes.
- Female chromosome pattern is designated as XX.
- A phenotype reflects an individual's physical and psychological traits.
Genetic Disorders
- Down syndrome is characterized by an extra chromosome.
- Phenylketonuria is not sex-linked.
- Sickle-cell anemia affects the body’s red blood cells.
Twin Development
- Identical twins originate from a single fertilized egg, resulting in genetically identical individuals.
Environmental Interactions
- Adoption studies assess the relative influence of environment and heredity.
- Active genotype-environment correlation occurs when an individual's environment supports natural talents.
- Passive genotype-environment interaction describes how parents influence their children's genetic predispositions through environmental opportunities.
Prenatal Development
- A fertilized ovum is termed a zygote, with the germinal period encompassing the first two weeks post-conception.
- The endoderm layer of an embryo develops into the digestive and respiratory systems.
- The fetal period lasts approximately seven months on average.
Prenatal Medical Procedures
- Amniocentesis involves sampling amniotic fluid surrounding the fetus.
- Ultrasound sonography uses high-frequency sound waves to visualize the fetus.
- Organogenesis marks a critical period when organs are most vulnerable to environmental factors.
Teratogens
- Teratogens are environmental agents that can cause birth defects and can affect organ functionality.
- Common teratogens include substances like alcohol, leading to low birth weight in exposed infants.
Maternal Health
- Women should confirm their immunity to rubella through blood tests prior to conception.
- An at-risk pregnancy can arise from incompatible Rh factors between parents.
- Folic acid deficiency in pregnant women can result in conditions like spina bifida.
Parental Influences
- Babies with Down syndrome are less likely to be born to mothers under 30 years of age.
- Maternal stress elevates the risk of prematurity in infants.
Birthing Process
- The birthing process is comprised of three distinct stages.
- During childbirth, fetuses secrete hormones to cope with delivery stress.
- Complications like toxoplasmosis can occur during delivery.
Support and Delivery Methods
- A doula provides support throughout the childbirth process.
- Oxytocin is a synthetic hormone that aids in stimulating labor contractions.
- Cesarean deliveries are generally safer than delivering a breech baby.
Infant Classification
- Preterm infants are classified as those born three weeks or more before full-term pregnancy.
- Apgar scores assess newborn health; a score of 3 indicates an adequate response to delivery stress.
- The Neonatal Intensive Care Unit Network Neurobehavioral Scale evaluates at-risk preterm or substance-exposed infants.
