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.

The counting and identification of chromosomes in the karyotype of an individual can diagnose aneuploidies, diseases caused by an alteration in the number of chromosomes in relation to the normal number in the species.. The name karyotype is given to the set of chromosomes of an individual, usually when visualized and identified under the microscope. The visualization generally takes place when the cells are undergoing the initial phases of cell division, so tha the chromosomes may be seen already replicated and condensed.
