Main features :
1) Quantitative genetics is an extension of mendelian genetics firmly based on mendelian principles of heridity
2) It provides ways and means for the study of polygenic variation which is not possible by mendelian genetics.
3) It deals with continuous variation.
4) Its estimates are based on means, variances and covariances.
5) It helps in better understanding of genetic principles and better planning of crop improvement programmes.
