          Mendelian Genetics Chapter 10 section 2 mendelian genetics Introduction of Mendel Gregor Joha Mendel was borne in 1822. He died in 1884. He was a priest. He formulated two laws of heredity: (a)   Law of segregation (b)   Law of independent assortment. Mendel presented his findings to Brunn Society for the study of Natural Science in ...

Mendel’s Law Of Segregation   It states that two coexisting alleles for each trait in an individual segregate from each other during meiosis and each gamete receives only one of the two alleles not both. Mendel’s law of segregation has four parts: I. Alternative versions of genes cause variations in inherited characters. This is the concept of alleles. Alleles are ...

Diffusion And Factors affecting the diffusion Diffusion The movement of molecules from higher concentration to lower concentration is called diffusion. Diffusion occurs down the concentration gradient. It is a spontaneous process. Diffusion continues till dynamic equilibrium is achieved. It follows laws of thermodynamics. But it is a very slow process. The rate and the direction of diffusion of different substances ...

Tissue Types & Tissue System The tissues, i.e., complex of cells are of two types: Meristematic Tissues: It is a tissue composed of immature, not well differentiated cells which has the capacity of division. Meristems: The term Meristem is derived from a Greek word Meritos meaning Divisible. It emphasizes the cell division activity characteristic of the tissue which bears this ...

HISTORY OF GENETICS   chapter 10 section 2 mendelian genetics Mendel’s laws: The laws of inheritance were derived by Gregor Mendel. He was 19th century Austrian monk. He was conducting plant hybridity experiments. Between 1856 and 1863, he cultivated and tested some 28,000 pea plants. His experiments brought firth two generalizations. They later became known as Mendel’s Laws of Heredity ...

Colloidal System – Properties & Significance A heterogeneous mixture in which solute particles are larger than molecules or ions but cannot be seen by naked eye is called colloidal solution. A system which shows properties of colloidal solution is called colloidal system. Its example is clay in water or starch in water. The solvent is called the dispersion medium in ...

­The Cell Wall Cell wall is a characteristic of a plant cell and it distinguishes it from the animal cell. The cell wall is considered as an Ergastic Substance, i.e., secreted by the living substance (protoplasm) but it-self is non-living. The synthesis of cell wall is controlled by Golgi complex. Three layers of cell wall can be distinguished: Middle Lamella: ...

Plant Anatomy Internal Organization The plant body is divided into stem, leaf and root. Evolutionary studies suggest that organization of oldest land plant was very simple resembling leafless and rootless Devonian plant, Rhvnia. If seed plants have evolved from these plants then the leaf, the stem and the root would be closely related phylogenetically, ontogcnelieally. The organs have common origin ...

Cucurbitaceae – Cucurbita maxima (Kadu), Cucurbita Lower Classifications The family comprises of 100 genera and 850 species distributed mainly in tropical and sub-tropical regions of the world. Most members are cultivated for their edible fruits. The common are: Cucurbita maxima (Kadu), Luffa cylindrica (Ghia tori), Cucumis sativus (Cucumber), Citrullus vulgaris (Water melon) and momordica charantia (Karela). Distinguish Features of Cucurbita maxima ...
