Document Summary
Lecture 12: inheritance in populations. Saturday, november 8, 2014. Chapter 10 (10. 2 a,b&f) Chapter 16 (16. 1 and 16. 2) Independent study outcomes: genetics of human abo blood groups. Abo blood groups show multiple alleles in systems with both codominance and dominance. Blood type a = antigen a = antibody b = acceptance of a or o. Blood type b = antigen b = antibody a = acceptance of b or o. Blood type ab = antigen a &b = no antibody = acceptance of a, b, Blood type o = no antigen =antibody ab = acceptance of o: strategy to distinguish between a phenotype that results from codominance relative to incomplete dominance. Occurs when effects of recessive alleles can be detected to a certain extent. Blend of two different alleles to create a new phenotype. Flower colour: white and red are parent alleles. Offspring would be pink (mix of two phenotypes)
