In this article we will discuss about the Mendel's experiment with garden pea plant. In 1856 Mendel began his experiments on plant hybridisation with garden peas in the monastery garden. Although similar work had already been done by contemporary botanists, the significant features of all these experiments had been overlooked because the investigators made overall observations of all inherited characters [...]
In this article we will discuss about the Mendel's tri-hybrid and multi-hybrid crosses. Mendel extended his observations to tri-hybrid crosses involving three pairs of contrasting characters. The characters he considered were: seed shape—smooth (S) vs. wrinkled (s); colour of cotyledons—yellow (Y) vs. green (y); and flower colour—violet (V) vs. white (v). The F1 hybrid produces 8 types of gametes. These [...]
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 [...]
