Document Summary

Every cell in body has 46 chrs (23 pairs), except for the egg/sperm cell. Dna encoded in combo of bases (adenine, thymine, guanine, cytokine) Chromosome: tightly coiled molecules of deoxyribonucleic acid (dna), carrying genes. Allele: an alternative forms of a gene that produces diff characteristics. Polygenic transmission: a given characteristic is controlled by 2 or more genes. Genotype: the specific genetic makeup of an indiv. Phenotype: the observable characteristics produced by the genetic commands. Dominant genes: the particular characteristics controlled by a gene will be displayed. Humans have about 25,000 genes (less than expected, and about the same as a fruit fly) Recessive genes: the particular characteristics controlled by the gene will only be displayed if the partner gene inherited by the other parent is also recessive. Recombinant dna procedures: enzymes cut dna, put back together. A major limitation of these kinds of procedures is that few behaviours = controlled by single gene.
