Lecture 11 IS- Inheritance of Variation I 1. Arrangement of genes and alleles on homologous chromosomes in a dihybrid organ- ism - each gene for each characteristic has their own allele 2. How independent assortment creates 4 different products of meiosis from a dihybrid parent - the alleles of the genes that govern the two characters segregate independently during formation of gametes - because each gene segregates independently, and the random alignment of homolo- gous chromosomes in meiosis I makes it so that the gene for colour can be delivered in- dependently to the gene for shape - this allows the parents to make four possible products with equal possibility 3. Application of the sum and product rule of probability - when the probability of two things are independent to each other (ro
