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 [...]
In this article we will discuss about:- 1. Recombination in Neurospora 2. Gene Mapping in Neurospora 3. Genotypic Control. Recombination in Neurospora: The fungus Neurospora crassa has some advantages for study of crossing over. In the vegetative phase of its life cycle, there is growth of filamentous, coenocytic hyphae to form the haploid mycelium. Sexual reproduction is achieved by coming [...]
