Questions - Assignment Example Some of the differences between mitosis include but not limited to, mitotic cells divide once whereas meiotic cells divide twice. Mitosis results in cell replication as for meiosis, genetic recombination and production of reproductive cells being the sole aim. Mitosis doesnââ¬â¢t yield exact copies whereas meiosis does. Mitosis also gives rise to diploid cells while meiosis gives haploid cells. DNA crossover occurs only in meiosis (Armstrong, 2007). As for similarities, duplication of an organismââ¬â¢s genome takes place only once preceding any other duplication in both processes. There is the existence of metaphase plates, centrioles in both (Armstrong, 2007). Basic steps of division are the same for both. Mitosis and meiosis occurs both in eukaryotic cells. Finally, both represent reproduction processes. A wild population contains tall and short plants. In one cross, two parental tall plants yield all tall progeny. In another experiment, two short plants are crossed and all progeny are short (cross 2). In the third experiment (cross number 3), two different short plants from cross 2 are crossed and 23 tall progeny and 77 short progeny are observed. The F1 generation came about through selfing of F1 plants. While maintaining Mendelââ¬â¢s first law, law of segregation, where the gamete is formed when each member of the allelic get disjointed from their other member. Confirmation of accuracy of his law through selfing of F2 plants yielded all tall and short plants respectively (Tornqvist, 2006). This can be depicted using a Punnet square as depicted on the next
