On the basis of shape the proteins may be of- (i) Fibrous protein- when the axial ratio of length : width of a protein molecule is more than 10, it is called a ‘fibrous protein’. example- alpha-keratin from hair, collagen, elastin etc. (ii) Globular protein- when the axial ratio of length: width of a protein [...]

The population which is infinitely large and formed of a group of such individuals which have the same chance of mating and producing progeny, provided they are sexually mature and of opposite sex. Panmictic units are integrated into the more or less complex systems of populations composing the species.

The proportion of one particular type of allele to the total of all alleles at this genetic locus in a breeding population is known as gene frequency or allele frequency. The proportion of frequency of any particular genotype among the inviduals of a population is known as genotype frequency. If any population of 200 individuals [...]

The principle that both gene and genotype frequencies will remain in equilibrium in an infinitely large population in the absence of mutation, migration, selection and non random imating.
