Document Summary

Lecture ten: we would expect a 1 year old to recover from traumatic brain damage more quickly than an adult. Nature (something we"re born with) vs nurture (something we learn). Genes: strand-like molecules of dna, linked on chromosomes, karyotype: the genetic blueprint of each individual. 22 autosomes + sex chromosomes (23rd pair: dna code for rna which codes for protein molecules (sequences of amino acids, the influence of genes is through protein synthesis. Why not answer nature: environment can influence protein synthesis as well, genes determine range of possibilities, but not degree of expression. Environmental exposure at a specific interval is critical. Under genetic control, but the environment can turn it on or off. White-crowned sparrow must hear adult song between 7th and 60th day. Outward characteristics may not indicate underlying genetic contribution. The variation of the gene (the different colours for the same part) Locus is the location on the dna strand.
