Document Summary

Phenotype- the observable characteristics produced by that genetic endowment. Genotype- the specific genetic makeup of the individual. Chromosome- tightly coiled molecule of deoxyribonucleic acid (dna) that is partly covered by protein. Genes- the dna portion of the chromosome carries the hereditary blueprint in units called genes. Polygenic transmission- a number of gene pairs combine their influences to create a single phenotype trait. Recombinant dna procedures- researchers use certain enzymes to cut the long thread-like molecule of genetic dna into pieces, combine them with dna from another organism, and insert them into a host organism, such as a bacterium. Gene knockout- procedure done with animals consists of altering a specific gene in a way that prevents it from carrying out its normal function. Heritability coefficient- the extent to which variation in a particular characteristic within a group can be attributed to genetic factors is estimated statistically by a heritability coefficient.
