ENV200H1 Lecture Notes - Lecture 12: Allosome, Allele Frequency, Sickle-Cell Disease
Document Summary
Two cell division processes: mitosis (cell cloning) Cell division that produces two identical daughter cells (the kind of cell division associated with growth and cell replacement: meiosis (gamete or egg and sperm production) Cell division that produces daughter cells with half the original number of chromosomes (the kind of cell division associated with reproduction ro production of new individuals) 1 a and 1b, 2a and 2b and 3a and 3b. Each gamete is going to end up with one allele of chromosome 1(a or b) one allele of chromosome 2 (a or b) and 3(a or b) Each of the 8 million and gametes has an equal chance of being fertilized by one of 8 mill and other gametes. 8, 388, 608 x 8,388, 608 = 70, 368,744,177,644 (each of us is a 1 in 70 trillion event)-so to find a clone of yourself you have a 1 in 70 trillion chance.
