Document Summary

In the field /natural enviro where behavior occurs: strength: see actual everyday events, limitation: cant control conditions, structured ob, lab situation set up to evoke behavior, strength: equal chance to display behavior. Genotypes/phenotypes: genotype : genetic makeup of an individual, phenotype: observable characteristics of an individual. In cell that store/transmit genetic info: dna, gene: segment of dna. Mitosis and meiosis: mitosis, process by which dna duplicates, produces new body cells, meiosis, sex cells (gametes) form, halves number of chromosomes present, leads to genetic variability. Autosomes, sex chrom. , and sex cells: autosomes: 22 matching pairs of chrom, sex chrom: 23rd pair of chrom (xx=female xy=male, gametes: sex cells, sperm and ovum, zygote: formed when sperm and ovum unite. Twins fraternal/dizygotic: result from release and fertilization of two ova, look dif, dif dna, etc. identical/monozygotic, result when a single zygote separates to form 2 individuals, look the same, same gender, same dna.
