Dr. Lange discovers a colony of bacteria living in an
extremely acidic environment. While observing the colony,
she finds that the bacteria are autotrophs
Which best describes the bacteria discovered by the
scientist?
They are probably archaebacteria because they are
autotrophs
They are probably eubacteria because they are
autotrophs
They are probably eubacteria because the colony lives
in an extreme environment
They are probably archaebacteria because the colony
lives in an extreme environment.

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?
