Document Summary
Use of research to attain problem solving. Mendel"s theory of independent assortment is shown via this method. These scientists put bovelli and mendel and accredited mendel with meiosis. Mendel tested 7 traits, on the 7 chromosomes of peas: this led to the law of independent assortment, he looked at more traits, but decided to do simple first, then complex later. Because we found that there are more complex rules to this, independent assortment only holds true for those on separate chromosomes. Meiosis produces one random crossover per arm on average. Mendel rules are violated, and often this is the reason. We can often figure out certain applications via this. Two varieties of sex chromosomes: breaks the pair-single-pair law, because of x vs. y. Mother nature has different determinations (female vs. Male: grasshoppers (xx vs. xo, birds (zw vs. zz, bugs (diploid vs. haploid) This explains the drone of male bees: reptiles (warm vs.
