Frequency of Dominant Alleles 0 Dominant alleles not necessarily more common in populations than recessive alleles o Polydactyly is a dominant trait If one or 2 copies of the allele is present 1400 us babies born wit extra fingers or toes 0 Two recessive alleles is far more prevalent than the populations dominant allele Keywords 0 Pleiotropy most genes have multiple phenotypic effects 0 Multiple symptoms of hereditary diseases like cystic fibrosis or sicklecell o Epistasis gene at one locus alters the phenotypic expression of a gene at a second locus o Albinism 0 Quantitative variation varies along a contimuum usually indicates polygenic inheritance effect of two or more genes on a phenotype 0 Eg skin color in humans 3 or more loci Pedigree Analysis 0 A pedigree is a family tree useful because humans are not good subjects for genetic research 0 Generation time is too long 0 Parents produce relatively few offspring o Breedingexperiments o Recessively Inherited Disorders 0 Sickle cell disease affects one out of 400 African Americans I Hemoglobin gene 0 Cystic Fibrosis common lethal genetic disease in the United States striking one out of every 2500 people of European descent I CFTR gene Dominantly Inherited Disorders Huntington s Disease 0 Dominant alleles that cause a lethal disease are rare and arise by mutation o Huntington s disease is a degenerative disease of the nervous system lethal 0 Why is it passed on if lethal o No obvious phenotypic effects until individual is about 35 or 40 yrs old Fetal Testing 0 In amniocentesis the liquid that bathes the fetus is removed and tested 0 In chorionic villus sampling CVS a sample of the placenta is removed and tested 0 Ultrasound and fetoscopy assessed in utero 0 Some genetic disorders can be detected at birth by simple tests that are now routinely performed in most hospitals in the United States o Tests before implantation in vitro 1 Whyxsnmwummdmmexpennmnmmdez cmkolgmw AA mlg lyxmpsdrmmmyemm wmbenyezd EJW39Mmummal
