Document Summary

Chromosomes and genes: gregor mendel pea plant experiment, founded idea of dominance and heredity. How tall u grow versus how tall u actually grow. Malleable: chromosomes: molecule of dna, contains many genes, genes: contain genetic blueprint, every cell has 46 chromosomes, 26 pairs. Form new cell with 46 chromosomes: heredity encoded in combinations of bases adenine, thymine, guanine, and cytosine. Acgt: genes contain bases, carry codes for protein manufacture. Dominant, recessive and polygenic effects: heterozygous: has dominant and recessive trait but we see dominant, homozygous: same trait. 2 dominants or 2 recessive: polygenic effects: when multiple genes contribute to the phenotype. The human genome (project): every single base needed to be identi ed, gured that humans have 25000 genes, before that people thought 100,000. 200 may have been from bacteria from early ancestry. Twin studies: twins reared together and reared apart, familial environment had little or no effect.
