Question

migration continues at a constant rate of 20% per generation with a starting allele frequency of 0.5 and a frequency of 0.9 in the migrating group, how many years does it take for the allele frequency to equal or exceed 0.7 in the original population if one generation takes 2 years? 1 ) 4 years . 2) 6.22 years 3) 8 years 4) 3.11 years

Consider two populations, I and II, with initial frequencies of q0 = 0.8 and q0 = 0.2, respectively. What is the change in gene frequency after one generation and its ultimate value in population I if migration occurs from population II to I at a rate of 3% every generation? How many generations of continuous migration will it take to halve the gene frequency of population I?

If a mainland population of snails has an allele frequency of 0.5 and an island population has a frequency of 0.2, how many generations of one-way migration (to the island) are required for the island population to achieve an allele frequency of 0.4, given a migration rate m = 0.01?

1. Calculate the average time, in generations, to fixation of an allele that starts at proportion 0.4 in populations of sizes 25, 33, 100, and 1000 Calculate the average time, in generations, to loss of an allele that starts at proportion 0.4 in populations of sizes 25, 33, 100, and 1000. Calculate the average time, in generations, to loss of an allele that starts at proportion 0.1 in populations of sizes 25, 33, 100, and 1000. Remember, both fixation or loss of an allele result in a decline in genetic diversity. Are alleles lost or fixed more rapidly in small or large populations?

00:01 So we are considering these populations.
00:03 So when we say this populations in an ecosystem they are considered.
00:10 And we can say this hardy -winberg equilibrium it is here.
00:15 So this hardy -winberg equilibrium, it is established in the population.
00:20 So what is happening? there is an initial frequency of 0 .8, that is kow -not in this population.
00:27 And q note they are 0 .2 respectively so the hardy fingberg equilibrium it is a basic rule so this is a basic law that will help to calculate the genotype so what is the hardy binberg equilibrium it is p square plus 2 p q plus kue square that will be equal to 1 so this is a homozygous this is heterozygous and this is also q it is also homozygous but it is also in the recessive trade.
00:59 So this particular thing it is here.
01:01 So we are considering this hardy being born equilibrium.
01:05 So what is happening? the probability in this case we are considering...
