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 [...]
The below mentioned article provides note on multiple alleles. After Mendel first advocated the existence of two factors for each character, it was demonstrated in many organisms that a gene consists of a pair of alleles. Each member of the pair of alleles is said to occupy an identical position or locus on each of the two homologous chromosomes in [...]
