Animal Breeding systems

The design of a breeding programme is a never-ending process - markets change, livestock change, technologies change, and humans change. There are however some proven breeding programmed that have withstood the test of time. It is important to first understand animal...

Now that the process of cell division (mitoses and meiosis) is understood, it can be seen that the process of meiosis is the reason we study genetics. The effect of additive and non- additive genes This basic introduction ton genetics-- the cell, genes and DNA; how...

As we grow, why don’t the cells just get bigger instead of sub-dividing? Cells are limited in size because the outside (cell membrane) must transport food and oxygen to the parts inside. As a cell gets bigger, the outside is unable to keep up with the inside, because...

The process whereby genes form proteins is very complex and controlled within each cell. Through 2 major steps, known as transcription and translation, specific protein structures are formed. Gene expression takes place through the combined...
