independent variable in biology

It is the modern theory on organic evolution. It is a synthesis of the ideas from the theory of natural selection and the mutation theory. The theory is the outcome of the thinking of recent biologists such as Huxley, Haldane and Dobzhansky. Neo-darwinism is based on three principles namely; genot..

The idea of independent assortment can be explained as follows: 1. Let us think of two pairs of contrasting characters represented by the alleles R and r, Y and y. There are two ways by which the two homologous chromosomes segregate during metaphase I of first meiosis. This in turn leads ..

The cell whether in a unicellular organism or a multicellular organism is capable of exhibiting some of its functions independently. Thus, the cell shows functional autono..

The nephron is the structural and functional unit of the kidney. Each nephron functions as an independent unit and produces a miniscule quantity of urine. The nephron can be differentiated into the following regio..

It refers to the variation of genes within a species. The genetic diversity enables a population to adapt to its environment and to respond to natural selection. The amount of genetic variation is the basis of speciation. Genetic diversity within a species often increases with environmental va..

Mendel could not note linkage because of the seven characters be studied in garden pea, most of them are located in different (non-homologous) chromosomes seed colour and flower colour are in the same chromosome i.e, they are linked. However, they lie so far apart that they get separated by crossin..

In the year 1902, Boveri and Sutton proposed the idea of chromosome theory of inheritance which was subsequently confirmed by Morgan in the year 1933. According to this theory, the Mendelian factors which are now called as genes, are located on the chromosomes and it is the chromosomes which ..
