Our genetic material, dna, is formed from a 4 letter "alphabet" of bases: a, t, g, c (adenine, thymine, guanine, and cytosine). the order in which the letters are arranged is important, but because a molecule can move, there is no difference between a sequence and the same sequence reversed. for example, the sequence (a, a, t, a, g, a, t) is the same as the sequence (t, a, g, a, t, a, a). (in reality, dna molecules have identifiable ends, but ignore that in this problem.)

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?

The picture shows a location in india that is very dry and arid. notice the tall mountains in the background; you can find high amounts of vegetation on the other side of the mountains. which statement is most likely true for this area?
