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 [...]
Recombinant DNA has opened new avenues for the study of gene function. The function of a cloned gene can be investigated by introducing the cloned DNA into eukaryotic cells. In simple eukaryotes such as yeasts Saccharomyces cerevisiae, molecular clones of various mutants have been prepared for genetic analysis. Like bacteria, yeasts offer advantages in having a small genome of about [...]
In this article we will discuss about the meaning an classes of DNA polymorphisms. Meaning of DNA Polymorphisms: Different alleles of a gene produce different phenotypes which can be detected by making crosses between parents with different alleles of two or more genes. Then by determining recombinants in the progeny, a genetic map can be deduced. These are low resolution [...]
