In some third world countries "cyanide fishing" for aquarium trade is allowed. Cyanide fishing uses the cyanide to "stun" fish and make them easy to catch. But the cyanide combined with handling stress has led to a mortality rate in the captured fish somewhere between 60% and 80%. Knowing this, how might this method impact the environment?
A) Cyanide is a safe chemical, so there will not be any effect on the environment.
B) Increase cyanide levels in the water will increase the biodiversity in that area.
C) Since so many fish are being caught, there is more room for predators to flourish.
D) It could lead to over fishing, since more fish have to be caught due to the high mortality rate.

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?
