In a laboratory experiment of sexually reproducing plants, a certain trait is determined by a single gene. The dominant allele has complete dominance over the recessive allele, resulting in two different phenotypes. Scientists created a new population of this plant by crossing 51 homozygous dominant individuals with 49 homozygous recessive individuals. The following results are from the first five generations of this population: Generation - Number of individuals with dominant trait - Number of individuals with recessive trait - Total number of individuals 1 - 51 - 49 - 100 2 - 285 - 0 - 285 3 - 270 - 90 - 360 4 - 315 - 105 - 420 5 375 - 125 - 500 On the basis of the data, propose an explanation for the phenotypic changes from generations 1 to 3. Do you think this population is in Hardy-Weinberg equilibrium?

Approximately 90% of all cases of polycystic kidney disease are inherited in an autosomal dominant fashion. the disease is typically related to mutations to genes (pkd1 and pkd2). pkd genes can be found on chromosome 16. the disease occurs in approximately 1: 800 to 1: 1000 people. here is a hypothetical example. the dominant allele d will cause the development of pkd. the recessive allele is known as d. what genotypes would correspond to suffering from pkd? dd, dd what genotypes would correspond to being normal (not suffering from pkd)? dd consider that 1: 1,000 people have pkd in your population of 325million. consider that pkd is inherited in an autosomal dominant fashion. show you math for all of the following questions: what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is p? what is q? how many people in your population would have pkd?
