There are two population A (N = 500) and B (N=50). Due to genetic drift, both populations will lose its genetic diversity in a generation. Such losses become magnified over many generations. After 20 generations, what will be lose its original variation?

#Section 3: Genetics, Cellular and Molecular Biology

  1. Both populations will lose 20% of its original variation

  2. A population will lose 20% of its original variation, but the B population will lose 50 %.

  3. A population will lose 10% of its original variation, but the B population will lose 20%.

  4. A population will lose 2% of its original variation, but the B population will lose 20 %.

In a sewage-treatment plant, a large concrete tank initially contains 440 000 litres liquid and 10 000 kg fine suspended solids. To flush this material out of the tank, water is pumped into the vessel at a rate of 40 000 litres h- 1. Liquid containing solids leaves at the same rate. Estimate the concentration of suspended solids in the tank at the end of 5 h._______________________.
