raditional breeding has generated significant genetic gain over time. However, this strategy falls short of yielding information on the biological processes involved. Additionally, there are great difficulties for the genetic improvement of characteristics which are measured solely in one gender and/or late in the life span of the animal. With the development of DNA chips it became possible maximizing genetic gain by reducing the generation interval and increasing the intensity of selection. The

Selection for desirable phenotypes has been practiced in cattle since their domestication approximately 10,000 years ago. This process, alongside breed development and genetic improvement programs, has led to the vast diversity of cattle breeds known today. Traditional breeding methods, grounded in quantitative theory, have facilitated continuous genetic gains in most economically important traits. However, until recently, selection has been conducted without knowledge of the specific genes infl

Selection for desirable bovine phenotypes has been practiced since the domestication of cattle, which occurred approximately 10,000 years ago. This process of domestication has brought about a marked change in behavioral and morphological characteristics in the subspecies and, together with the development of breeds and genetic breeding programs, has given rise to the enormous variety of patterns and racial types known today. Since then, traditional breeding tools, based on quantitative theory,
