PSYC 2400 Lecture Notes - Lecture 4: Gene Expression, Heredity, Thalidomide
Document Summary
Chapter 2 wrap up assignment due sunday 2/9 including regular ch 3 assignments. 40 mc questions- think about mc, they are like the clicker questions and online quizzes. Skipping the body: physical growth and development. Many sources of genetic and environmental variability. Vrtually no outcome is 100% guaranteed (even with strong genetic basis) Mendel (1822-1844- pea plants, recessive vs. dominant traits) Individuals differ from one another by only about . 1% to 1. 5% of their genes. The interplay of genes and environment is very complex. Humans share over 90% if their dna with their primate cousins. Gene expression differs across species in ways that help explain each species" distinct bio and behavior. Much of the differences among humans, chimps and rhesus monkeys is due to reg mechanisms. Phenotype- the observable expression of the genotype, including both bod characteristics and behavior. Environment- every aspect of an individual and his or her surroundings other than genes. Genetic material is asson on as chromes.
