[THE DEVELOPMENT AND SURVIVAL OF TOXOCARA CANIS EGGS IN THE NATURAL CLIMATIC CONDITIONS OF GORNO-ALTAISK]
Abstract:
The time of development and survival of Toxocara canis eggs in the soil of Gorno-Altaisk was experimen- tally investigated in 2011-2014. In July 2011, T.canis eggs matured at 3-5-cm soil depths from the stage of 1-2 blastomeres to invading larva within 12 days at a daily average temperature of +23°C and at a relative humidity of 82%. At 3-5-cm soil depths, more than 70% of invaded T. canis eggs preserved their viability through- out the experimental period (4 years). The paper gives evidence for the seasonal survival of invaded T. canis eggs in relation of the length of soil stay.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
