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...
