Definitions • Homologous Chromosomes: Chromosomes
that are the same length and have the same genes, but not necessarily the same alleles.
• Genes: DNA that encodes for a function such as eye color.
• Alleles: versions of genes. • Genotype:The allelic makeup (which alleles
organisms has). • Phenotype: The appearance of an organism.
