A population of cottontail rabbits feeds on grass located at the bottom of a cliff. A loose boulder at the top falls and kills a large portion of the rabbit population randomly. How will this affect the subsequent generations of cottontail rabbits in this population? 1.The cottontails that survived will reproduce and be able to better avoid large boulders 2.The subsequent generations will be less diverse than the original population 3.The population will find another food source to avoid injury from environmental factors 4.Cottontail rabbits will likely go extinct due to their feeding patterns

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?
