Document Summary

Every cell has 46 chromosomes (23 pairs) These molecules have the ability to direct the assembly of proteins that build the body. This genetic protein assembly can be turned on and off by the environment, or by other genes. Found about 25, 000 genes but expected to find more. Found more than 75 genes that contribute to hereditary diseases genotype - specific genetic makeup (dna analysis) Present from conception. as soon as mother and father come together that"s your genotype phenotype - observe characteristics - if you are male or female, eye color height, etc. Recessive - little letter characterisic displayed if. Polygenic transmission (multiple gene pairs influence phenotype genetic engineering - ex genetically modified food products recombinant dna procedures - Or can we vary the genes in the same environment? study of genetic relatedness heritability coefficient - estimate of how much characteristic is due to genetic factors.
