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. [...]
After reading this article you will learn about:- 1. Determination of Recombination Value from the F2 Data 2. Determination of Recombination Value from Backcross (Testcross) Data. Determination of Recombination Value from the F2 Data: Four methods are available to estimate recombination value from the F2 data. For each of these methods, the F2 data given earlier to detect linkage is [...]
After reading this article you will learn about the chi-square test and its interpretation. In genetic experiments, certain numerical values are expected based on segregation ratios involved. However, in actual field experiments exact values may not be obtained due to in-viability of certain pollen grains, zygotes, no germination of some seeds, or even death of few plants after germination. This [...]
