I have decided to do my research on pigs. I choose this topic because my favorite animal is a pig, and I would like to get to learn more about them. The question I am researching is “ Are pigs better than any other livestock and if so why?” I also want to find out what types of pigs are there. And which one is the best to keep as a family pet and why. In my research I discovered that there are two types of pigs, one of them is Asian pigs, and the other is European pigs. They came about around the 18th -19th century and migrated into China. I also learned that Asian and European pig populations were domesticated from different ancestors and that they are expected to have different genetic diversities. I also discovered that genetic diversity is smaller in a pig than a human and other livestock. European and Asian breeds may have extended linkage disequilibrium (LD). Linkage disequilibrium is also a causation of mutations in pig breeds. In my research I also discovered that the heterozygosity ranged from .35-.60 with an average of .5 across 17 autosomal chromosomes in the European pig breeds. The European values were close to the Asian values. The Asian values were .429 – .67. The heterozygosity was expected to be much higher.

Very technical terms used here, make sure that you define them in your paper.
Everything in the second half of the paragraph was a bit confusing. I agree you should define them more.
