It is a cross involving two pairs of contrasting characters. For this experiments on dihybrid inheritance. Mendel selected the contrasting characters in the seed coat and cotyledons. He conducted a cross pollination between a pure breeding plant with round seed coat and yellow coloured co..

Monohybrid Inheritance - In the initial set of experiments, Mendel concentrated only on the pattern of inheritance of a single pair of contrasting characters. This pattern of inheritance involving only one pair of contrasting characters is known as monohybrid inhe..

(aabbcc) in 1/64 individuals. fig. 18.13 - Quantitative Inheritance of Skin Colour in Human Beings In this situation, each dominant gene directs the synthesis of the same amount of the pigment melanin, which is responsible for skin colour. Hence, the shade of the skin colour is directly r..

Chromosomal Basis of Inheritance - Heredity depends upon the protoplasmic continuity between the parent and the offspring. It is the gametes that establish the continuity between parent and offspring and hence, the mechanism of inheritance operates across this exceedin..

Heredity depends upon the protoplasmic continuity between the parent and the offspring. It is the gametes that establish the continuity between parent and offspring and hence, the mechanism of inheritance operates across this exceedingly slender protoplasmic bridge. The ma..

The rediscovery of Mendelism and the subsequent idea of chromosomal basis of inheritance, paved way for several significant discoveries in the field of heredity. Many other patterns of inheritance which cannot be explained on the basis of Mendel's laws alone, were disc..

According to Lamarck the characters acquired by an organism are transmitted by heredity to the next generation. In every generation, fresh characters are acquired. With the result, after many generations, the changes accumulate to the extent that the species becomes modified into a new o..

Summary - The mechanism of transmission of characters from the parental generation to the offspring is called heredity. The differences seen among members of a species and their offspring are described as variations. Genetics is the study of heredity, variations and the environm..
