In the Lesser Pahoa Kipuka Chicken population, the frequency of individuals born without bones is 1/2500 individuals. Assuming that only half of the individuals homozygous recessive for the "boneless" allele survive to reproductive maturity, determine both the selection coefficient (s) as well as the mutation rate (µ) required to explain the persistence of the allele in the population due to mutation-selection balance.

µ =____x 10-4

b) rare SNPs can have a big effect on common, complex disease risk
c) risk of common, complex diseases can be accurately predicted using common SNPs
d) genetic risk factors are not important in common, complex diseases
e) the best strategy to identify genetic risk variants in common, complex disease is whole exome sequence

The comammox bacteria play a role in nitrification and therefore in the nitrogen cycle. Other microbes, with distinct ecological niches, also participate in the nitrogen cycle. The metabolic reactions involving nitrogen that bacteria perform include: nitrogen fixation (N2 → NH3), nitrification (NH3 → NO3- or NO2-), and denitrification (NO3- or NO2- → NO, N2O, and N2), all of which make up the nitrogen cycle. Each of these reactions is carried out by a unique set of microorganisms with a distinct ecological niche.
Drag the appropriate items to their respective bins.
A. microbes that oxidize inorganic nitrogen compounds B. obligate anaerobes C. chemoorganotrophs D. chemolithotrophs E. obligate aerobes F. facultative aerobes Bin 1. Nitrogen fixation Bin 2. Nitrification Bin 3. Denitrification |
