The first step for the policy analyst is to identify the space in which the policy problem exists. This is generally a broad policy space, such as health policy or environmental policy. Next the analyst defines the specific policy issue area.olitical feasibility is a measure of how well a solution to a policy problem, will be accepted by a set of decision makers and the general public.
Preparing a Karyotype. Metaphase cells are required to prepare a standard karyotype, and virtually any population of dividing cells could be used. Blood is easily the most frequently sampled tissue, but at times, karyotypes are prepared from cultured skin fibroblasts or bone marrow cells.None of the leukocytes in blood normally divide, but lymphocytes can readily be induced to proliferate, providing a very accessible source of metaphase cells.lood is easily the most frequently sampled tissue, but at times, karyotypes are prepared from cultured skin fibroblasts or bone marrow cells.

Twenty-two of the paired chromosomes are similar in males and females and are called autosomes. In the female, the twenty-third pair consists of two X chromosomes. In the male, the twenty-third pair consists of one X chromosome and one Y chromosome. A karyotype is a pictorial representation of an individual's chromosomes. Cell division and chromosome duplication. The fertilized egg, or zygote, begins as one cell containing forty-six chromosomes, and the number of cells increases by mitosis, a process of cell division that produces new cells containing duplicates of all forty-six chromosomes. The gametes are formed by a process of cell division called meiosis.
