Coin Sex Lab

In this lab, we flipped coins to demonstrate how meiosis works. Alleles are randomly chosen in recombination to determine the genes of the offspring. The coins acted as the alleles, the opposite sides being chosen as we flipped them. We could determine the probability of certain traits by using a punnett square. For Sex of Offspring, we expected 50% to 50% for having a male or female. The coins we flipped represented x-linked inheritance, because it determined the sex of the child. We got what we expected, because five out of our 10 flips were girl, and five were boys. For autosomal dominance, we predicted 50 percent of the 10 children would be bipolar. This represented autosomes. We got 5 children would have bipolar disorder, what we predicted, Bb, heterozygous, meant a bipolar individual. bb, homozygous, meant that the child was healthy. The Dihybrid cross- Looking at two traits together demonstrated diybrid crosses, as opposed to a monohybrid cross, which is the inheritance of a single trait. Most of our results were almost exact with our predictions. Using probability will never be 100% sure, because mutations can happen. In my life, I could use this if I ever have children and want to see what traits they could get.
