How large are the DNA differences between different breeds of dogs?
In an issue of the journal Science, researchers wrote that the genetic differences between different breeds of dogs are unusually pronounced, so much so that they can determine a dog's breed based solely on its DNA. This phenomenon is related to humans controlling inbreeding in dogs over the past 300 years to obtain different dog characteristics. This shows that humans can indeed play an important role in the field of species evolution. When researchers analyzed the DNA genetic code of dogs in an attempt to further understand the genetic factors of human diseases, they were surprised to find that, in just the past few hundred years, not

Pear storage methods are different and require tailored treatment
Master the storage characteristics of pears. Generally, early-maturing varieties do not store well, while mid- and late-maturing varieties and white pear varieties (such as Ya pear) store relatively well. The storage temperature for pears is generally -1°C to 3°C, and the relative humidity is 90% to 95%. Ya pear, Xuehua pear, Ci pear, Changba pear and others are extremely sensitive to carbon dioxide and low oxygen, and are not suitable for controlled atmosphere storage. During storage, be careful to prevent water loss. Pear fruits contain a lot of water, and once they lose water severely during storage, rotten spots, rotten fruit or hollow dried fruit will appear. Therefore, attention should be paid to increasing the humidity in the warehouse

Key Points on the Differential Diagnosis, Prevention and Control of Newcastle Disease and Avian Influenza in Chickens
Newcastle disease and avian influenza in chickens are both highly contagious diseases caused by viruses. They can occur in all four seasons, and both are more common in winter and spring. In poultry farming production, both diseases occur frequently, and the losses they cause are very serious. The vast majority of farmers attach great importance to this and have intensified various prevention and control efforts, but they are not very clear about the differences between these two diseases. The following is a comparison of Newcastle disease and avian influenza in chickens from several aspects including pathogens, clinical symptoms, and pathological changes. Pathogens: fowl plague and avian influenza
