1. Transmitting new combinations of gene variants (alleles) between generations. 2. In organisms like ourselves, we’re diploid dominant: adult form of the organism (a child could be considered an adult biologically) are diploid. There are some diploid cells that will go through division to produce haploid gametes (sperm and eggs) The haploid cells will form diploid at fertilization. The fertilized zygote produces the trillions of cells in an adult organism. 3. Analogy: each book is instructional. Each book is a gene - will provide instructions for one particular task. Those instructions are found in collections (together on a bookshelf) - the whole bookshelf is a chromosome. There aren’t empty spaces on chromosomes, though. Sometimes space filling objects would be tables of contents - indicating some type of information that’s important within space. For any given set of instructions, there’s a locus (the position of a set of instructions on a particular chromosome). 4.
