INTRO TO PSYCH 1
1- genes and evolution
genome- complete set of genetic material
human genome project- map entire structure of genetic material- order of molecules
that make up each of the thousands of genes on each of the 23 pairs of human
chromosomes
phenotype- observable characteristics- genetics+environment influence
genotype- genetic constitution of an organism- genes received at the moment of
conception
allele is a specific variant of a gene
homozygote and heterozygote chromosomes/ allele that is a different version of a
gene on locus of chromatides
cells become specialised, depending on which of their genes are expressed
chromosomes- 23 pairs contained in cells + made of DNA (=2 intertwined strands of
molecules in double helix shape) + store information in
