Biology Notes on Quantitative Variations | Genetics

The below mentioned article provides notes on quantitative variation. The classical experiments in Mendelian inheritance demonstrated transmission of obviously well-marked, distinct pairs of contrasting characters (tall vs. dwarf; yellow vs. green cotyledons, etc.). Moreover, the two alternative expressions of a phenotype were controlled by a single gene which strictly obeyed the rules of dominance to produce visible qualitative differences between [...]

Inheritance of Kernel Colour in Wheat | Genetics

In this article we will discuss about the inheritance of kernel colour in wheat. Nilsson-Ehle performed many crosses between varieties of wheat having red seeds and those having white seeds. In all crosses except one the F2 generation gave a ratio of 3 red to 1 white. In the one exceptional cross he used a very old red variety from [...]

Genotype and Phenotype Variations of Corolla in Plants | Genetics

In this article we will discuss about the genotype and phenotype variations of corolla in plants. East in 1910, 1916 performed experiments on flower length in Nicotiana longiflora. He took two homozygous, pure breeding lines differing in flower length, one having 41 cm the other 93 cm for average length of corolla. The minor variations in flower length within a [...]
