In this article we will discuss about the concept of gene conversion. In eukaryotes reciprocal exchange between loci almost always produces reciprocal recombinants. In Neurospora the linear arrangement of ascospores in the ascus indicates directly which strands have exchanged segments during crossing over. Thus after meiosis in a heterozygote Aa, due to reciprocal exchange the 8 ascospores are arranged in [...]
In this article we will discuss about the Hardy-Weinberg law with its applications. In 1908, the mathematician G. H. Hardy in England and the physician W. Weinberg in Germany independently developed a quantitative theory for defining the genetic structure of populations. The Hardy-Weinberg Law provides a basic algebraic formula for describing the expected frequencies of various genotypes in a population. [...]
In this article we will discuss about the role of Hardy-Weinberg Law in random mating of population. Hardy-Weinberg Law is applicable only when mating is random. When genotypes do not mate at random it is called nonrandom mating, that is, individuals with certain genotypes prefer to mate with individuals of certain other genotypes. Consider for example the case of albinos [...]
