The Concept of Inheritance
Explain the concept of inheritance
Gregor John Mendel advanced the principles of inheritance. In 1856 – 1863 Mendel grew and tested some 29,000-pea plants. From these studies, he formulated the law of segregation and the law of assortment.
After his work on peas, Mendel began to experiment with honeybees. However, he failed to produce a clear picture of their heredity because of difficulties in controlling the mating behaviour of queen bees.Mendes works was largely criticized and generally rejected during his lifetime. It was only after his death that his work gained broad recognition. He is now considered the father of modern genetics, Mendel diedMendel died on January 6th, 1884.
Mendel chose the garden peas because of the following reasons:
It is self-pollinating but can be cross-pollinated
It matures very fast
It produces many seeds and hence many off springs
It has several physical properties
Some of the characteristics that be studies were:
Height of the stem-tall or dwarfs
Texture of the seed coat – smooth or wrinkled
Colour of flowers – purple or white
Colour of pods – green or yellow
Position of flowers – axial or terminal
