Document Summary
Genetic: differences in phenotype due to differences in individual"s genotypes, 2. Environmental: differences in phenotype due to differences in external surrounding or conditions experienced by individuals, snakes eating different coloured mice might have different coloured skin, 3. Genotype x environment: differences in phenotype due to differences in the effect of external conditions on individuals with different genotypes. Genetic variation: ex. variation in the type of proteins that encode genes, amount of proteins produced, differences in timing or location of expression of genes, ex. If you taste bitterness than it might not be good for you: can this type of variation evolve? compounds, yes, because individuals produce offspring that carry different alleles. Huntington"s disease: progressive brain disease, caused by insertion of many copies of cag triplets in the htt gene. Silent site substitution: point mutation that does not result in amino acid change, no change in protein, 2.
