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.

In this unit, we will learn that gender describes those characteristics, roles and behavior patterns that distinguish men from women and are socially and culturally defined. These perceptions are quite in contrast to sex roles that are biologically determined. We therefore learn that there is a distinction between gender and sex.

The discipline of sociology is founded on a trinity of three main pillars: social structure, social research methods and social theory. You may like to think of the discipline of sociology as a traditional African stool that stands on three legs: socialstructure, social research methods and social theory. Having been introduced to the discipline of sociology last semester, this course exposes you to the first pillar: social structure. As you go on with your courses in sociology you will encounter the other two pillars: social research methods and social theory

The word photography was coined in 1839 from the Greek terms 'phos' for light and graphs meaning to write or draw or record. photography is therefore nothing more than graphic recording of light energy of different intensities. the scope of photography is now understood to include all processes that are used to record the action of radiant energy on different forms of matter.

This is a very exciting course which many social science scholars have termed as the Queen Mother of all social sciences. Many people not schooled in sociology liken it to socialization which is incorrect. Socialization is a small part of sociology and shall be covered in due course. In this course all sociological concepts will be introduced to you. This is an interactive instructional module that uses both action and collaborative learning styles that provide you with diverse online learning experiences and effective learning processes. The key purpose of this module is to expose you basic sociological concepts and knowledge enough to illuminate your interest in social sciences and particularly sociology. The intention is to equip you with the necessary intellectual infrastructure to analyze societal structures and processes with the aim of creating and furthering positive reform

It contains all the notes related to database and database management systems.

In this lesson we will discuss mutually exclusive and exhaustive events, and also probability.

Moments are popularly used to describe the characteristics of a distribution and are measured about a point.

The measures of central tendency are not sufficient measures to reveal the shape of the distribution of data set. The measures that show the spread of a data set are called the measures of dispersion. The main measures of dispersion are range, inter quartile range, standard deviation, variance and coefficient of variation. In this lesson we will discuss these measures of dispersion.

Statistics is the science of data. This involves collecting, classifying, summarizing, organizing, analyzing, and interpreting numerical information.

One of main objectives of statistical analysis is to obtain one single value that describes the characteristic of the entire mass of unwieldy data. Such a value is called the central value or average value. In this lesson we will consider some of central values which are commonly used.

In this lesson we will discuss the other measures of location or measures of central tendency namely, geometric mean, harmonic mean, median and mode of given data.

Over the last fifty years, several theories have been put forward to explain the process by which children learn to understand and speak a language. They can be summarised as follows:
