Interactions: Genetics and Reproduction
Tremendous genetic improvements have occurred in the dairy cattle population. The progress has been due to the identification and the subsequent availability of superior sires through artificial insemination (Al). Since 1973 a new technology, embryo transfer (ET), has provided an additional avenue for genetic progress. The genetic and economic returns from this technology remain subject to the ...
متن کاملThe need for interaction between assisted reproduction technology and genetics: recommendations of the European Societies of Human Genetics and Human Reproduction and Embryology.
Infertility and reproductive genetic risk are both increasing in our societies because of lifestyle changes and possibly environmental factors. Owing to the magnitude of the problem, they have implications not only at the individual and family levels but also at the community level. This leads to an increasing demand for access to assisted reproduction technology (ART) and genetic services, esp...
متن کاملAsexual reproduction: Genetics and evolutionary aspects
Reproduction is essential to all organisms if they are to contribute to the next generation. There are variousmeans andways of achieving this goal. This review focuses on the role of asexual reproduction for eukaryotic organisms and how its integration in a life cycle can influence their population genetics and evolution. An important question for evolutionary biologists as to why some organism...
متن کاملJournal of Assisted Reproduction and Genetics
Purpose: To evaluate the drop-to-drop and pellet-to-pellet repeatability and stability of frozen sperm pellets. Methods: Ten pellets were thawed per batch (low and normal concentration) and evaluated by two investigators to establish a quality control chart. Then low and normal concentration pellets were thawed and evaluated daily for 10 days by both investigators. The values for both investiga...
متن کاملGenetics of Reproduction: Considerations for Sire Selection
genetic selection to improve economically important traits. Most recently, much of that progress has been through the implementation of expected progeny differences (EPDs). Expected progeny differences make it possible to compare the genetic merit of two or more animals for any number of traits. Most EPDs involve growth or carcass traits, because most producers are paid by the pound, or in some...
