PSYCH 101 Lecture Notes - Lecture 12: Gregor Mendel, Punnett Square, Reuptake
Document Summary
~ 25,000 genes, 3. 3 billion base pairs. Every three base pairs codes for an amino acid, combinations of amino acids create proteins. Most of the chromosome is intergenic, in other words, it is in between genes and is not actually a gene. Many of the genes are not actually expressed so most mutations do not have. In some cases, the mutation has an effect, in which case it will either increase or decrease the organism"s chances at survival (and is either passed/not passed on) For example, intelligence is linked to less children, therefore from an evolutionary psychology perspective, being less intelligence is more advanced. The scientist who discovered basic genetics (punnett square) Phenotypes are the actual expression of genes. He discovered the idea of alleles, which are passed on by the parents. Alleles can either be dominant or recessive. Transporters are proteins that facilitate re-uptake, which is part of how serotonin levels are regulated.
