How can heterozygosity be used to measure the strength of drift?
Homework Answers
Heterozygosity refers to the presence of two different allele ( example Aa ) at one or more loci . And genetic drift refers to change or variation within a small population due to change in the relative frequency of the anotomical structures which causes disappearance of particular genes. So it affects small population . So it has got the ability to reduce the heterozygous allele in a small population . So heterozygosity can be used to measure the strength of drift. When the genetic drift is more heterozygosity is less . When the genetic drift is absent the heterozygosity is more .

The current heterozygosity of an isolated population of lemurs is 23%. The effective population size is estimated to be about 50. How many generations will it take for heterozygosity to fall to 15% due to drift?

5. (2 marks) A balance can be used to measure the strength of the magnetic field. Consider a loop of wire, carrying a precisely known current, shown in the figure, which is partially immersed (80 % of the total cross sectional area) in the magnetic field. The force that the magnetic field exerts on the loop can be measured with the balance, and this permits the calculation of the strength of the magnetic field. The short side of the loop...

Select all of the statements about genetic drift that are true. It can cause alleles to be lost in a population by chance. Genetic drift causes allele frequencies to change because only the strongest individuals in a population are reproducing Its strength is proportional to the size of a population -the larger the population, the greater the force Smaller populations experience greater changes in allele frequency due to genetic drift than large populations. It is a random process with respect...

5.3. A Hall effect device is used to measure the strength of an external magnetic field. The device is oriented in the way described in Fig. 5.1. It is made from a cube of p-type silicon with hole concentration cm3 where the length of each side of the cube is 1 mm current of 3 mA is applied through the device. The voltage measured across the device is 2.4 mV. Find the strength of the external magnetic flux density, |B|.
