In this article we will discuss about the chromosome theory of inheritance. In order to understand the role played by chromosomes as carriers of hereditary material, we must turn the clock backward to some landmarks in the history of genetics. The earliest records date back to the work of the 18th Century plant hybridisers. One of them Kolreuter had some [...]
In this article we will discuss about:- 1. Meaning of Meiosis 2. Occurrence of Meiosis 3. Genetics 4. The Spindle Apparatus 5. Forces Required for Chromosome Movement 6. Regulation of the Cell Cycle. Meaning of Meiosis: The division which takes place in cells of the germ line is called meiosis (Fig. 6.2). It results in four products of a parent [...]
In this article we will discuss about:- 1. Introduction to Probability 2. Rules of Probability 3. Probability and Human Genetics 4. Binomial Expansions 5. Multinomial Distributions. Introduction to Probability: The numbers of individuals in each ratio result from chance segregation of genes during gamete formation, and their chance combinations to form zygotes. Since these are chance events, accurate predictions about [...]
