Selection is an important technique in plant breeding. It involves picking the healthiest and the best ones out of the entire crop and reproducing them under controlled condition..

. Criteria for selection may be different in different crops or different objectives. Crop Criterion for selection Objective Rice More spikelets / panicle, bold spikelets, larger panicle Increasing yield Cotton More number of fruits/ plant, Bigger fruit size Longer fibre, more m..

Darwin believed that nature selects only those individuals, which have favourable variations and thereby have competitive advantage over others. This process is known as natural selection. The members of any particular species can develop and survive only when they are able to ..

B and T lymphocytes have specific receptors on their surface. In B cells, this receptor is the antibody produced by that cell. When this receptor interacts with the antigenic determinant specific to it, the B lymphocyte becomes activated and divides to form a clone of cell..

The selectivity of a catalyst is its ability to make a reaction proceed in a particular direction to yield a particular product. This aspect of a catalyst can be well understood with examples. Example 1: The reaction of CO with H 2 yields different products when different cata..

One student is selected from 100 students in a school. What is the probability that the selected student is not among a group of 10 particular students? => 1.1 or 1.2 or 0.9 or None of the above..

Some electrolytes contain more than one type of cations or anions. When one type of ions is discharged in preference to the other, under certain conditions of electrolysis, it is known as selective discharge of ions. The following are the factors that influence the ..
