cross multiplication method

Test Cross - Mendel devised a system of conducting verification for the results obtained by him. It is known as test cross. It is a cross between F1 plant and the recessive parent. A test cross-conducted for the monohybrid inheritance results in the two oppos..

Let a be the smaller positive angle with cos a = k. Then, cos(- a ) = k cos q = cos a and cos (- a ) A = q or - a Also, any co-terminal angle with above is trigonometrically equivalent and so has the same cosine. q = (Any even multiple..

Nature has evolved certain methods which self-pollination is prevented and cross-pollination is favoured. Given below are a few such adaptatio..

It is a method by which two or more different crops are grown together in the same soil. A mixed cropping of ragi with pigeon gram replenishes the soil because pigeon gram fixes the atmospheric nitrogen, which goes into the soil in the form of nitrates. From the soil these nitrates are u..

Solve the proportion a 4 = 7 9 using the property of cross multiplication. => 5 9 or 28 23 or 28 9 or 9 28..

Point of intersection of two lines - Then (x 1 , y 1 ) lies on both (i) and (ii). Solving for x 1 and y 1 by the method of cross multiplication, we obta..

Crop improvement by deliberate attempt to cross two parents of desirable characters to incorporate such characters in next generations is called breeding. The entire process of pollination, fertilization and regeneration is kept under control and selected parents are allowed to reproduce ..

Breeding - Crop improvement by deliberate attempt to cross two parents of desirable characters to incorporate such characters in next generations is called breeding. The entire process of pollination, fertilization and regeneration is kept under control and selected parents are allowed to..

Desirable plants are selected purely based on phenotype and pooled. They are allowed to be grown in mass in next generation. Further selections are made in 3-4 such generations to consolidate desirable characters by ignoring plants with undesirable character at each selection. Individual progeny is..

Cell division is a method by which new cells are originated from pre-existing cells. The formation of daughter amoebae in amoeba, the development of sex cells and the growth of a young animal or plant into an adult, all involve cell multiplication..
