Answer #1

Yes.

Genetic drift may be defined as the irregular or random fluctuations in gene frequencies from generation to generation in a small sized population due to sampling errors.

Fluctuations in gene frequencies may cause fixation of one allele and extinction of other allele. It is very clear that its a random event.its not 'driven' by some thing.it is due to the phenomenon of probability in which purely chance events determine which alleles within a reproctive population would be carried forward and which ones to disappear.

    QUESTION 4 1 points Save Answer One metric of genetic diversity in a population is heterozygosity, i.e., the frequency of heterozygotes. For the marker(s) that are not in Hardy-Weinberg equilibrium, does the difference between Ho and He indicate increased or decreased heterozygosity for those markers? Increased heterozygosity Decreased heterozygosity QUESTION 5 2 points Save Answer Select all the mechanisms of evolution that could explain the deviations from H-W expected frequencies for those markers, based on the difference in heterozygosity?

    please briefly explain your idea about the following paragraph. Genetic engineering is a process of modifying the characteristics of an organism by manipulating the organism’s genetic material. As technology advances and genetics and genomics become more and more explored, it is possible in the near future to see genetic engineering occurring in embryos in order to obtain desirable traits.  These embryos are frequently referred to as “designer babies” because with the use of genetic technology, parents may be able to alter...

    The questions about mechanism of evolution 1. If you send a sample of your cheek cells to the company 23andMeTM, they will tell you your genetic ancestry. This is possible because certain alleles are associated with certain historic human populations (eg, GATTC in a particular location might be associated with Han Chinese ancestry). Most of the allele differences have no effect on phenotype. The table below lists four mechanisms of evolution. For each mechanism, circle and explain whether you think...
