Mendel’s Experiment with Garden Pea Plant | Genetics

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 [...]

Mendel’s Tri-Hybrid and Multi-Hybrid Crosses | Genetics

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 [...]

Blood Group Alleles in Man | Genetics

In this article we will discus about the blood group alleles in man. The ABO blood group system in man provides an excellent illustration of a multiple allelic system. If blood from two persons is allowed to mix outside the body, sometimes it will mix well, at other times there is clumping (agglutination) of red blood cells. The reason for [...]
