Document Summary

Found to be strikingly similar in personality traits upon psychological testing. Genetics definitions: genotype, phenotype, genes, chromosomes, specific genetic make-up, observable characteristics produced by genotype, segments of dna that code for production of specific proteins, tightly coiled dna partly covered by protein. Dna portion holds genes": human cells have 46. Exception of sex cells which have 23 chromosomes each. 2 sex cells from parents combine to form new cell with 46 chromosomes. Gene organism: each chromosome contains numerous genes, one chromosome of every pair is from each parent, each nucleus contains 46 chromosomes. 2: each human cell (except rbc) contains a nucleus, human body contains 100 trillion cells. Gene effects: dominant gene, characteristic it controls will be displayed. Dark eye color: recessive gene, controls characteristic in absence of dominant gene. Only shows up when both genes are recessive i. e. ) Blue eye color: polygenic transmission, combined influence of pairs of genes. Genes combine influences to create a single phenotypic trait.
