In genetics, traits are classified into two groups based on their mode of inheritance and their effects on an organism’s phenotype: qualitative and quantitative traits.… Read More »Qualitative and Quantitative Traits and Their Inheritance in Animal Breeding
The assessment of most animal species reveals phenotypic differences between individuals. For example, in cattle, there are noticeable differences in coat color and the presence… Read More »Variations in Animal Population and Their Implications in Breeding
To study an animal population, a statistical description of the population is required. This description, in its simplest form, consists of a measure of central… Read More »Measurements of Variation in Plant and Animals Population
Genes hold the information to build and maintain an organism’s cells and pass genetic traits to offspring. However, some genes are incompatible with life and… Read More »Types of Genes
Within a population, sexual reproduction enhances genetic diversity because the genetic material of offspring comes from two sources. For most species of animals and some… Read More »Sex Determination Mechanism in Animals and Plants
The fundamental laws of inheritance were derived from a series of experiments with garden peas over a century ago. Gregor Mendel crossed different pure lines… Read More »Mendel’s Laws Of Inheritance
The absence of a clear theory explaining inheritance hindered progress in animal breeding for many years. However, the rediscovery of Mendel’s rules at the beginning… Read More »Historical Perspectives of Heredity in Animal Breeding
Improved animal health is a major objective in animal breeding strategies. Selection for genetic disease resistance provides a potential avenue for improving the health status… Read More »Principles and Challenges in Breeding Animals For Disease Resistance
The techniques for improving animals involve principles of selection based on quantitative variations. It is not possible to obtain all desirable traits in one individual.… Read More »Principles and Challenges in Breeding Animals For Increased Productivity
As advances in genetics have confirmed and illuminated the mechanisms underlying Mendel’s observations, the need to adapt and modify his principles has also been discovered.… Read More »Types of Gene Action and Exceptions To Mendelian Ratio

Lipids are biological substances that are soluble in organic solvents. Apart from being structural components of biological membranes, they also play a major role in… Read More »Types and Function of Lipids in Animal Nutrition
Nucleoproteins play a crucial role as primary constituents of chromatin in cell division, reproduction, and the transmission of hereditary factors. Nucleoproteins and Nucleic Acids in… Read More »Structure and Function Nucleic Acids and Nucleoproteins
Amino acids are the smallest units obtained when complex proteins break down during digestion. Chemically, they contain carbon, hydrogen, oxygen, nitrogen, and sulfur. Amino Acids… Read More »Categories and Properties of Amino Acids in Agriculture
Proteins are a group of compounds containing carbon, hydrogen, oxygen, nitrogen (about 16%), and sulfur. In some proteins, phosphorus or iron is present, and occasionally,… Read More »Structure and Classification of Proteins
Carbohydrates constitute the primary organic components of plant structures and are present to varying degrees in all animal organisms. In plants, carbohydrates are synthesized through… Read More »The Chemistry of Carbohydrates in agricultural systems
A hypothesis is a statement or claim about a population, often making assumptions regarding a population parameter. For instance: i. The weight of an adult… Read More »Inference and Hypothesis Testing in Agricultural Research
Analysis of variance in agricultural research is a parametric statistical procedure widely used to analyze experiments involving two or more conditions of a single independent… Read More »Analysis of Variance in Agricultural Research
A research process begins with a research question. The researcher will formulate a hypothesis about the problem to be solved and then decide on the… Read More »Sampling and Data Collection in Agricultural Research
Probability is simply the chance that something will happen. Mathematically, probability is the extent to which an event is likely to occur, measured by the… Read More »Understanding Probability in Agricultural Context
Measurements or counting produce raw data, which on its own is challenging to interpret due to the lack of organization or summarization, rendering it less… Read More »Frequency Distribution in Agriculture
