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.

s=_____

µ =____x 10^-4

Please show work.

Expert Solution

Natural selection is an important evolutionary force which comes in play due to differential reproduction and survival of the individuals with different genotypes and phenotypes in the population. The individuals with larger reproductive success and survival will transfer their alleles to next generation, thus increasing the allele frequency related to the particular characteristics.

Mutation, a cause for variations in the population , is the sudden change in nucleotide sequences of the DNA, altering the combinations and introducing a new set up for alleles. This may either be advantageous or deleterious. If it is advantageous for the survival and reproductive fitness of the individual, it is selected against the non-advantageous, and vice-versa. Natural selection helps in elimination of harmful recessive alleles.

Selection Co-efficient (s) is a measure of fitness of the individuals with different characteristics in the population. It shows the extent of natural selection acting on a particular genotype in the population.

In the Republic of Pecunia 1100 individuals are born in period t. The population grows according to Nt = 1.1Nt−1. Each citizen in Pecunia is endowed with y1 = 15 units of the consumption good when young, and y2 = 5.5 units when old. Preferences are such that individuals will always want to consume more than their endowment when old. The fiat money stock in period t amounts to 2500. The Pecunian government is increasing the stock of fiat money...

Please show the detailed calculation steps. 1) In a population of 2500 lizards the alleles determining skin colour show incomplete dominance, and the following phenotypes for each genotype are observed. 200 are homozygote CRCR with red colour, 1500 are homozygote CGCG with green colour and 800 are heterozygote CRCG with brown colour. a) What are the frequencies of the CR & CG alleles from counting the number of alleles in the population? b) The following season the population had grown...

A population-based study of 451 acoustic neuroma patients and 710 age-, sex-, and region-matched individuals without neuroma was conducted in Sweden between 2002 and 2007. Cases were identified from clinical records at two specialty hospitals in Stockholm. Patients were included if they had been diagnosed with either histologically- or imaging-confirmed acoustic neuroma. Occupational exposure was based on historical measurements of occupational noise (321 job titles summarized by a job exposure matrix) and self-reported occupational noise exposure. The researchers also evaluated...

In a population of snow hares, 1 out of 5,000 hares are born with a dark-haired coat, which is a recessive phenotype. A decadal study showed that the relative fitness (w) of these individuals was 0.1. What mutation rate would be needed to maintain this phenotype? If the mutation rate is actually ~1.0 x 10-8, how could the occurrence of this genotype best be explained?
