Title: How would the genotype and allele frequencies change in the 2nd generation? Post by: MightofMjolni on Sep 15, 2012 Suppose that of a population of 100 individuals, 25 could not taste PTC and that the individuals in that population who could taste this chemical decided only to marry other individuals who could taste PTC.
How would the genotype and allele frequencies change in 2nd generation? This is an example of what evolutionary force? Can somebody help me solve the problem? This way I would understand the question better? This is to Sandy_6489: What would you say to the evolutionary force? Title: How would the genotype and allele frequencies change in the 2nd generation? Post by: migatomio on Sep 16, 2012 the person who have cant taste PTC, is the recessive allele and the other one is the dominant, so tt * with either Tt or TT so the genotypes would have two possiblities:
100% Tt or 25%tt, 25% TT, 50% Tt. Title: How would the genotype and allele frequencies change in the 2nd generation? Post by: Smntnl on Sep 16, 2012 The evolutionary force is an example of prezygotic barrier of behavioral barrier. Since PTC non-tasters are recessive the number of PTC non-tasters will decline and PTC tasters will rise.
