The below mentioned article provides a note on overlapping genes. It is now becoming apparent that in both prokaryotes and eukaryotes a nucleotide sequence can code for more than one protein. The nucleotide sequence of a gene may be translated into a complete polypeptide chain. Then a part of the same sequence may also code for another protein of a [...]
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 [...]
One way of measuring genotype frequency is from phenotype frequency. Consider the case of 3 blood groups A, AB and B determined by two alleles IA and IB at a single locus. In a random sample of 1000 humans, the A group occurred in 210, AB in 450 and B in 340 individuals. The frequencies of the blood group phenotypes [...]
