Document Summary
Ecological environmental: micro = family, meso = social-cultural environment, exo = human-built environment, macro = macro. Development = part nature, part nurture: heritability. Degree to which different traits are influenced by genetic factors. Development = interplay of nature and nurture. Stem cells: ability to renew themselves through mitotic cell division and changing into a diverse range of specialized cell types: embryonic from blastocysts, adult adult tissue. Genes: direct the cells of an embryo to become a human being. No two human beings have the exact same genes. Observable characteristics = phenotype; things we have that are observable, ex. hair color. Determine risk and, perhaps, prevention: down syndrome, sickle cell anemia, cystic fibrosis, huntington disease, neurofibromatosis, alcoholism, cancer. Dna banking: families with genetic disorders, for future development of genetic testing and diagnosis, cord blood banking. Wide range of methods now employed to bring children to those unable to reproduce naturally.
