The science of genetics is relatively new. Modern breeding designs and molecular capabilities have accelerated the pace and scope of understanding the nature of inheritance, variation, and phenotype expression, promising a biological revolution… but, the fabric of this revolution is woven with historical terminology, and ultimately has to address classical insights, ideas and observations. In turn, classical ideas and focus were based on a very long unrecorded tradition of animal and plant breeding

Modern bread wheat is a hybrid species derived from three crosses between low yielding grass species, around 10,000 years ago in the region bounded by Syria/Iraq/Turkey. These grasses appear to have been cultivated, selected and bred for yield and adaptability to a range of conditions.

DEFINITIONS… Genetics is defined as (1) “ The study of genes” (2) “ The study of inheritance .” (Griffiths et al. 9e) or , the study of two apparently paradoxical observations: individuals resemble their parents yet they are different from them . In other words, genetics deals with problems of heredity and variation (Lewontin 1974) Genetics can be studied on different natural scales of organization: molecular, chromosomal, transmission genetics, population genetics, evolutionary genetics.
