ploidy indicates the number of complete sets it contains What is the difference between haploid, diploid and polyploid? - haploid (n) the number of distinct types of chromosomes present (ex: humans & fungi) - diploid (2n) are organisms that have two homologs of each chromosome and have two alleles for each gene (ex: humans) - polyploid are organism with three or more sets (ex: plants) How does understanding what homologous pairs of chromosomes are to help us understand how the overal...

These are the notes used to study for and during the exam for Organismal Biology 1, aka BIOL 112. They include underlined sections that are important or were emphasized during class and other assignments/review sessions.
