A population of green iguanas lived on a tropical island. Originally, most of the iguanas had feet without webbing between their
toes and a long round tail A few iguanas had webbed feet and a short, flat tail. As the years passed, the island became smaller
and smaller because of flooding. Even the land areas were dotted with ponds and pools. The iguanas had a hard time finding the
food they normally ate. To survive, the iguanas had to swim from island to island to find food.
How would you expect the iguanas to look many years after the island flooded and food became harder to find?
The iguanas will look the same but there will be less of them.
There would be more iguanas with webbed feet and flat tails.
There would be fewer iguanas with webbed feet.
The iguanas would no longer be green

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?
