Unformatted text preview: colors. • Since diploid organisms have two sets of chromosomes (the homologous chromosome pairs), most "genes" are paired, often called the gene pair Alleles • The alternative forms or variations a gene can have, such as brown or blue for eye color, or red or white for flower color. • A diploid individual will have two alleles for each gene locus. • Within a population there can be more than two alleles for a gene, but only two alleles will be present in any one diploid individual. Locus • The region on a chromosome where a gene is located. • The alleles of a gene are located at equivalent places (loci) on the homologous chromosomes Homozygous • The 2 alleles for a gene are the same in an individual Heterozygous • The 2 alleles for a gene are different in an individual...
