5 Which of the following best explains why meiosis results i

Solution

Answer 3: The right side of the figure represent Tyrosine Kinase receptor. It is the second major type of cell -surface receptor. Ligand for this receptor are soluble and membrane bound peptides harmones. Binding of ligand stimulate tyrosine kinase activity, which subsequently stimulates a signal-transduction cascade leading to changes in cellular physiology and/or patterns of gene expression.

Answer 5: Meiosis produces four daughter cells which are haploid, meaning that there is only one copy of each chromosome in each cell. In meiosis the arms of different chromosomes may overlap, break and recombine before the division is complete. This process, called \"crossover,\" creates new combinations of existing genes within the haploid daughter cells. Each haploid cell produced by a parent organism contains half of the parent\'s genetic material. These combination maintains its genetic diversity. Asexually reproducing populations may be comprised entirely of clones and thus have very little or no genetic diversity. Therefore option B is most appropriate answer for the greater genetic diversity of meiosis than mitosis.
