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

         element: segment of desoxyribonucleic acid that controls design or complaisant system of a peculiarity/characteristic of the cell or organism. In the most cellular organisms 2 copies of the segment of DNA, termed Alleles, move to give back the situation form of the trait as seen.         autosomal component: constituent locate on an autosomal chromosome which is any of the 22 gay chromosomes (or 3 Drosophila chromosomes) separate than the X or Y. Autosomal genes 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 topic in phenotypic ratios of 3:1, 1:1, 9:3:3:1, and 1:1:1:1         Mendels rights: Laws of Dominance, Law of separatism of Genes, and Law of Independent admixture of Genes. annotating: Mendel was wrong in his final Law because he did not know slightly Linkage; it should have aver the Law of Independent florilegium of Chromosomes.         Codominance: Non-Mendelian condition in which in that location argon 3 glacial on the wholeeles for a gene. 2 of these alleles argon different rife versions of the gene. Therefore the possibility of A/B exists grown an AB blood type.         Gene pot: Total of all alleles for a particular gene in a population.

special(prenominal) allele/ genetic mutation could be rare as in albinism or comparatively common as in diabetes or cystic fibrosis.         Downs Syndrome: partial tone triploid condition in mankind where thither are 3 copies of chromosome 21. Unfortunately there are many forcible problems (heart, liver, kidney, brain, & facial) that are visible         Turners Syndrome: incomplete monoploid condition in humans where there is no pair in the X chromosome (often termed XO). Various physical changes chance in the phenotype including webbing of the cope and sterility.         Klinefelters Syndrome: Partial triploid condition...
