A group of students are playing in a pile of dried oak leaves on the way home from school. They found a few acorns (oak tree seeds) lying near the pile of leaves. One student asked, “Are acorns and oak leaves alive?”Another student replied, “Acorns and leaves are not alive. They don’t breathe, move, eat, or do any of the things living things do. How are they any different from a bunch of rocks?”Explain how you would respond to these students.

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?
