Description
Crop improvement can be defined as
i. An art, a science, and technology of improving the genetic makeup of plants in relation to their economic use for the mankind.
ii. The art and science of improving the heredity of plants for the benefit of mankind.
iii. Science of changing and improving the heredity of plants
2. Genetics
The study of heredity and the variation of inherited characteristics, the science of genetics enables plant breeders to predict to varying extents the outcome of genetic manipulation of plants. The techniques and methods employed in breeding are determined based on the genetics of the trait of interest, regarding, for example, the number of genes coding for it and gene action. For example, the size of the segregating population to generate in order to have a chance of observing that unique plant with the desired combination of genes depends on the number of genes involved in the expression of the desired trait.

FUNCTIONS
To understand the word function, we consider the following scenario and definitions. For example, the growth of a sidling is an instance of a functional relation, since the growth may be affected by variations in temperature, moisture, sunlight, etc. If all these factors remain constant, then the growth is a function of time.

Transistors
Trending!
Begin by reverse biasing the CB junction. Here we are showing an NPN transistor as an example. Now we apply a small forward bias on the emitter-base junction. Electrons are pushed into the base, which then quickly flow to the collector. The result is a large emitter-collector electron current (conventional current is C-E) which is maintained by a small E-B voltage

Transistor Bias Circuits
For the transistor to properly operate it must be biased. There are several methods to establish the DC operating point. We will discuss some of the methods used for biasing transistors as well as troubleshooting methods used for transistor bias circuits
