A new fossil called Darwinius was discovered in Germany. It lived around 47 mya. It had a small brain, short snout, and postorbital bar. Its diet probably included a lot of fruit and leaves. It did not have a dental comb. It had nails instead of claws and was probably an arboreal quadruped. Researchers disagree about whether the fossil is more similar to living haplorhines (the group that includes tarsiers, Old and New World monkeys, apes, hominins) or more similar to strepsirrhines (lemurs, lorises) Required:
a. Describe two features that the fossil shares in common with living haplorhines.
b. Describe two features that the fossil shares in common with living strepsirrhines.

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?
