Document Summary
Controls growth and development determines what someone will look like i. e. how tall and aspects of their personality. In b/w the sides of the latter of the double helix are the rungs. Gene is a segment of the dna. Can be 100 of the rungs of the letter to several million. Gene expression: genotype vs phenotype: genotype = specific genetic makeup, don"t see everything in the genotype. Recessive and dominant genes i. e. brown eyes = bb or bb discovered that there is more than one genotype for eye colour: gregor mendel and cross pollination experiment (peas and flowers) / he discovered dominant and recessive traits. Forms of gene expression: dominant-recessive one dominates aka mendelian inheritance. Co-dominance and incomplete dominance neither dominant, or one dominant - doesn"t hide effects of other: co-dominance: both expressed i. e. calico cat, blood type = ab, blood type o is recessive.
