what are the mechanisms of heredity

Heredity - An important result of the reproductive cycle is production of similar featured individuals for generations. The transmission of characteristics through successive generations refers to heredity. These characteristics include all physical, physiological and psychologi..

Heredity and Variation - All living organisms reproduce. Reproduction results in the formation of offspring of the same kind. A pea plant produces only pea plants each time it reproduces. A rat produces only rats. Humans produce only humans. However, the resulting offspring need not and m..

Summary - Heredity may be defined as the transmission of characteristics through generations Variation may be defined as differences among individuals of a species Both heredity and variation play important roles in evolution of organisms The study of the mechanism of ..

Pre-Mendelian Theories on Heredity - There have been several explanations on the possible mechanism of inheritance of traits from the parent to the offspring, put forth from time to time by different biologists. All these early theories presume that the characteristics of the tw..

There have been several explanations on the possible mechanism of inheritance of traits from the parent to the offspring, put forth from time to time by different biologists. All these early theories presume that the characteristics of the two parents somehow mix during inheritance...

Water moves through the gills by the coordinated action of mouth and the operculum. Taking in water and thereby oxygen is called inspiration and exit of water is called expiration. Mechanism of Respiration in F..

. The digestive system consists of mouth cavity, pharynx, oesophagus, stomach, small intestine and large intestine. Mouth cavity consists of tongue and two rows of teeth. Saliva secreted by three large salivary glands and other smaller glands gets mixed with the food by the action of the tongue and..

A low-dose x-ray source moves in an arc (360 o ) around a specific part of the body being scanned and repeatedly sends out x-ray beams. As the beams pass through the body, the tissues absorb small amounts of radiation. Once the beam passes through, they are converted by light sensitive crystal det..
