We were recently given the challenging task of figuring out who the parents of Morgan Koops are. Mrs. Koops was adopted at a young age, and her birth parents were never known by herself. Recently, the U.S. Adoption Agency contacted us to find out who the birth parents are. The parents of Mrs. Koops were narrowed down to five couples to start. All five of these couples are Russian. These couples included Nickoli and Svetlana, Igor and Yana, Vlad and Anna, Dimitry and Olga, and Boris and Natasha. We were given the various phenotypes for the couples in blood type, color blindness, eye color, hair color, hair line, chin shape, dimples, and earlobes. We were also given the family history on all of these various human characteristics. Then, …show more content…

We did this by using punnett squares and pedigrees. We would use the pedigrees because they were very similar to a family tree, but they would display who carried the dominant trait and who carried the recessive trait. We could also reveal whether the trait was heterozygous dominant or homozygous dominant. This would be decided by the parents of this individual. If one parent of the individual held the recessive form of the characteristic and the other parent held the dominant form, the individual would be heterozygous dominant. This could also be known as a hybrid form with their allele. If there was an instance where the majority if not all had the dominant trait in the pedigree, then it was a simple answer. If you had two parents that held the dominant trait and their parents held the dominant trait. Then, when deciding if the offspring of the first two parents would be homozygous or heterozygous, it would be homozygous. This would be because of the heredity unlikeliness of the possible heterozygous in these alleles of the relatives coming all the way down through the generations. You would then imply that this offspring would be a homozygous purebred. After finding the genotypes of the two individuals you want to have
