Biology 10 Notes on Genes, Chromosomes, Mendel's Laws, and Mitosis vs. Meiosis

         element: segment of DNA that controls design or kindly system of a trait/characteristic of the cell or organism. In the most multicellular organisms 2 copies of the segment of DNA, termed Alleles, act to give back the particular form of the trait as seen.         Autosomal component: constituent located on an autosomal chromosome which is any of the 22 human chromosomes (or 3 Drosophila chromosomes) another(prenominal) than the X or Y. Autosomal elements argon never sex-linked.         sex-linked Gene: Gene located in the un checkmateed region of the X chromosome or on the Y chromosome. These genes run for to be seen in males.         Mendelian Organism: Organism whose patterns of heredity follow Gregor Mendels 3 laws and tend to give offspring in phenotypic ratios of 3:1, 1:1, 9:3:3:1, and 1:1:1:1         Mendels rights: honors of Dominance, Law of Segregation of Genes, and Law of self-governi ng Assortment of Genes. annotating: Mendel was wrong in his final Law because he did not know about Linkage; it should catch read the Law of Independent Assortment of Chromosomes.         Codominance: Non-Mendelian consideration in which there argon 3 diametric on the wholeeles for a gene. 2 of these alleles are different dominant versions of the gene. Therefore the possibleness of A/B exists grown an AB blood type.         Gene Pool: Total of all alleles for a particular gene in a population.

special(prenominal) allele/mutation could be elevated as in albinism or relatively common as in d iabetes or cystic fibrosis.      !    Downs Syndrome: partial derivative triploid condition in mankind where there are 3 copies of chromosome 21. unluckily there are many physical problems (heart, liver, kidney, brain, & facial) that are visible         Turners Syndrome: Partial monoploid condition in mankind where there is no pair in the X chromosome (often termed XO). respective(a) physical changes occur in the phenotype including webbing of the neck and sterility.         Klinefelters Syndrome: Partial triploid condition...
