Review Questions - Lab #121) Let us say that global climate change makes it easier to raise goats in Sub-Sahara Africa. What doyou think goat herding will do to the lactase persistence (LP) allele frequency in Sub-SaharaAfrica?I think the lactose I will go downi2) Explain the mechanism by which the allele frequency might change.The frequency Might change it Move humans were exposedtoMilk and learned how to survive with it instead of Meat.3) According to the Gerbault paper, the LP allele frequency in old world South Africa was 0.1.Assuming that there are only two allele for this trait, what is the allele frequency for the non-LPallele?pindBibliographyGerbault, P., Liebert, A., Itan, Y., Powell, A., Currat, M., Burger, J., et al.

Lactose intolerant individuals cannot digest milk because it includes lactose; "lactose intolerant individuals lack the lactase enzyme, which hydrolyzes lactose into glucose and galactose, resulting in a range of symptoms." As per our policy, We are answering only question 1 as they are not the subparts of any question. For the rest of the questions please repost.Answer 1: The research is being carried out to demonstrate that earlier described genetic alterations are actually associated with lactase persistence in Africans. These genes are found in abnormally large numbers in African livestock tribes, and the results support the hypothesis that animal herding is intimately related to the development of lactose tolerance. Researchers concentrated on three areas of the human genome around the lactase gene: a promoter region that switches the gene on or off, triggering lactase synthesis, and two enhancer regions that keep the gene on or increase lactase output. Investigators analyzed these areas and discovered five mutations known to be linked with lactase persistence, which they tested in all of the various groups. Researchers verified the link between the three previously found enhancer area alterations and lactase persistence by correlating genomic data to field data. On examined mutation sequences (called haplotypes) on the chromosomes of individuals where the lactase genes were situated to learn about these mutations and where they originated geographically. According to the research, the distribution of lactase mutations paralleled the rise of people and cattle domestication across Africa.Conclusion: According to the study, the distribution of lactase mutations across Africa tracked the emergence of people and cattle domestication. Yes, goat herding will increase the lactase persistence (LP) allele frequency in Sub-Sahara region.
