Mendel’s Law of Inheritance From his work on the inheritance of phenotypic traits in peas, Mendel formulated a number of ideas about the inheritance of characters. These were later given formal recognition as Mendel’s laws of inheritance. These are outlined below. 1. The oocyte is the egg producing cell in the ovary of an animal. In the diagram illustrating the law of segregation above: a) State the genotype for the oocyte (adult organism). b) State the genotype of each of the four gametes. c) State how many different kinds of gamete can be produced by this oocyte. 2. The diagram illustrating the law of independent assortment (above) shows only one possible result of the random sorting of the chromosomes to produce: Ab and aB in the gametes. a) List another possible combination of genes (on the chromosomes) ending up in gametes from the same oocyte. b) State how many different gene combinations are possible for the oocyte.
