A population with an effective size of Ne=15 individuals that is evolving purely by genetic drift starts with an allele frequency p(A)=0.2.
a) What is the meaning of Ne and how does that differ from N?
b) What is the expected heterozygosity after 10 generations of genetic drift?
c) What will be the eventual heterozygosity after many years of genetic drift?

Answer #1

a)The Ne is called the effective population size and its differ from N or population size as it only takes that individuals of population which can reproduce and can add to the population whereas N involves all reproducing and non reproducing individuals of the population.

What is “effective population size”? Using hypothetical examples and numerical values, discuss the relevance of the concept of effective population size in planning and implementation of conservation programs. The effective population size (Ne) is related to the census number of individuals as follows. Ne = (4NmNf)/(Nm + Nf) 1/Ne = 1/t (sum of 1/Ni) is same as Ne = t/(sum of 1/Ni) Nm = number of males, Nf = number of females, Ni=population size at a given generation, t =...

You collect several thousand Drosophila melanogaster individuals from the UCD campus. You take 1000 flies, establish a population in the laboratory and maintain it at a size of 1000 each generation. You then establish from the remaining flies a series of replicated populations of size 10, 100, 200, and 500 and maintain each at the starting size (10, 100, 200, 500) for several generations. After some time you sequence each lab population. a. If one plotted for each lab population,...
