Coin Sex Lab

In this lab, we flipped coins to simulate the randomness of alleles. The coins were the genes and the sides were like the different alleles. This simulated the process of meiosis and the recombination of these genes. This showed how random it is. There is a very low chance of getting homozygous genotypes in dihybrid crosses. You can see what the probability of something is, but you'll never know what you will actually get. The coin flipping was also gene segregation and the results after flipping was the recombination. In part two we tested autosomal dominance, the ones on the 22 chromosomes. In part 3 we did an experiment on x-linked recessive traits, which in this experiment we used the allele for colorblindness. X-linked inheritance is the trait you get from the x chromosome. Monohybrid was the ones we did using only one gene. We also found the different probabilities for either heterozygous or homozygous phenotypes. For the first experiment, the females were homozygous x. Males were heterozygous. Our last experiment was dihybrid, and tested for the different colors of hair and eyes. It was wither brown or blonde hair and brown or blue eyes. This experiment showed that neither trait affected the other and it was possible to get lots of different combinations. This relates to our life because it shows what the probability is of getting certain traits for our offspring.
