Document Summary
Cell nucleus contains dna: carries genetic information for all living things is not learning, 23 pairs of chromosomes. Dna the ordering of the nucleotide bases determines the genetic code . Phenotype= how genetic makeup is expressed this is what you see. Example of mendel"s experiment dominant and recessive traits : neither dominant, or one dominant doesn"t hide effects of others cow and offspring got one brown and one white gene cow is. )ncomplete dominance: combination expressed (cid:523)black cow mated with white cow and offspring ended up grey or red. Co-dominance: both expressed (brown cow mated with white. Dominant-recessive: one dominates flower mated with white flower, offspring ended up pink) half white, half brown) Polygenic: many pairs of alleles create expression. When it comes to behavioral stuff in humans, whatever is responsible for the behavior is usually polygenic. Phenotype: =genotype + environment, +gene-environment interaction, +gene environment correlation.
