This paper argues that confounding between epigenetic and additive genetic effects explains the missing heritability problem, and offers two new epigenetic models describing transgenerational inheritance that may supplement the traditional mixed linear models used to make predictions of the additive genetic merit of animals. The new models utilize pedigree information and show the property of additivity, like the additive genetic models do. The combined predictions of both epigenetic and genetic effects may provide useful indexes that help farmers select replacement animals or breeding stock. The utility of these methods depends on data where both confounding and the parsimony of parameters come to bear on practical limits. The proposed epigenetic models are just a first step, and they may not win long-term favor when compared to future models that are still to be formulated.

First measurements with the help of several temperature sensors in a beehive show that a high heat input through solar radiation in a beehive leads to stress in the bee colony. The bees show cooling behavior that can be observed directly and with sound analyses in order not to let the temperature in the hive rise above 38°C. A measurement without bees shows a difference in internal temperature of up to 7°C in a comparison between a shaded and an unshaded hive. The heat input can be reduced by simple measures such as shading by placing a rear-ventilated radiation shield. It is recommended to shade hives in summer.

he coronavirus disease 2019 (COVID-19) is an exceptionally contagious and pathogenic viral disease brought about by the SARS-CoV-2 infection that was frst detailed at Wuhan, China, and later it spreads everywhere throughout the world. It was a severe acute respiratory syndrome (SARS)-like virus, and the primary host of this virus is bats, revealed through genome analysis. The intermediate medium between human and bats is still unknown, and it is quite contagious, resulting in rapid spreading of this disease. All things onsidered, there are no clinically endorsed medications or antibodies for this sickness, yet a few precautions and staying away from close contacts are suggested. The number of COVD-19 confrmed cases is rapidly increasing with higher mortality rates, more than other epidemics that occurred in the last century although it still fuctuates. We will analyze the COVID-19 outbreak situation considering confrmed cases, recoveries, mortality rate percentages, etc. India and Bangladesh are two geographically important countries, and we will also analyze the COVID-19 situation for these two countries either with similarities or differences.
