    Introduction Allozyme analysis is a technique which is used in study of genetics because it reveals the genetic variation that exists within a wide range of organisms (Gómez‚ 1998). Allozymes are different forms of an enzyme expressed by alternative alleles on the same gene locus (Micales & Bonde‚ 1995). Analysis of these allozymes can be done by protein electrophoresis. Protein electrophoresis involves the movement of proteins within an electric field with mobility being dependent on factors such

    1.) In a plant having two carried alleles for the color of a flower in a gene‚ with P for purple and p for white‚ the three possible combinations which might exist in any one plant are PP making a purple plant‚ pp to make a white plant‚ or Pp resulting in a ‘hybrid’ plant. 2.) Out of the genotypes PP‚ Pp‚ pp‚ the resultant flower colors are (as described above in exercise 1) are purple (for PP‚) purple or purplish-white (for Pp- likely purple as it is dominant‚ or a mixture of the colors‚) or white

    10.1 Mendel’s Laws Gregor Mendel‚ working in the mid 1800s‚ performed inheritance experiments using garden peas in an effort to discover how variation arose in offspring. Mendel’s Experimental Procedure Pea plants proved to be an excellent choice for Mendel’s experiments because of their reproductive mechanisms and the heritable traits they exhibit. Mendel used statistical analysis on his data from garden peas leading him to formulate his particulate theory of inheritance. One Trait Inheritance
