Unformatted text preview: Why Genes Matter 09/11/2007 10:03:00 ← Whatever genes are turned on in the cell will be expressed. • The gene on chromosome 11 will be turned on during red blood cell formation. • Even if there is an error, it will be transcribed and translated ← ← We can use genetics to predict offspring phenotypes if we can answer some questions. • Which allele is dominant? • What are the genotypes of the parents? • What inheritance pattern does the gene exhibit? ← ← Inheritance • Alleles : versions of a particular gene o There may be many different alleles for a gene in a population. o Gene = hair color. Allele = specific color. o An individual usually has 2 alleles for one gene. • Genotype o The genetic makeup of an individual o Homozygous : 2 copies if the same allele o Heterozygous : 2 different alleles for the same gene o Loci : location of the gene • Phenotype...
