Chapter 9: Patterns of Inheritance What pattern will inheritance follow? Why is it important? Always follow patterns? Rule of Probability In tossing a coin the odds of either a head or tail is always 50%. The outcome is unaffected by the previous attempt. If 2 coins are tossed‚ each will be dependent of the other HH‚ HT‚ TH‚ TT (Probability is 25% or ¼) The rules also hold true for genetics due to the law of independent assortment. Each alternative type of outcome in a gene acts independently

GENETICS JARGON Alleles (allelomorphs) Alternative forms of a particular gene. There can be several alleles of a particular gene in the population‚ but only 2 alleles can be inherited by a single individual. For simplicity much literature aimed at the general reader uses "gene" where it means "allele". Allelic Series A series of alleles that are all mutant forms of the same gene and are at the same locus (same position on the chromsome). Alternate Heredity Mendelian inheritance involving

W4Q1 Meiosis is the process by which cells divide and create living creatures. Without meiosis we cannot have the process of mitosis‚ which is the process by which cells of tissue are created for living creatures. When meiosis occurs 4 daughter cells are created‚ while only 2 are created in mitosis. With the creation of 2 daughter cells the new cells will be similar to the parent cell‚ but will have differences‚ as there more parent cells involved. When mitosis occurs the daughter cells will be

example of its magnetic influence towards the boys is when the littluns needed order they "obeyed the summons of the conch‚ partly because Ralph blew it and he was big enough to be a link with the adult world of authority" (58). Ralph gained automatic dominance due to his possession of the conch. If one is holding the conch‚ they immediately retain power‚ which is an example of democracy. Golding establishes the dominant and obvious control of the conch at the opening of the novel‚ with its beautiful colors

This time of night when thoughts are blurry and it is easy to slip into the unknown and the imaginary (“bright
