Intraindividual Variation of Meiotic Recombination Parameters in Pig Spermatocytes: A Preliminary Study
Abstract:
Meiotic recombination parameters like crossover (CO) rate or synaptonemal complex (SC) length are known to vary strongly between individuals and between cells from the same individual. The origins of this variability remain elusive, and little is known about the variations that might occur between different samples and/or over time within the same individual. To document this question, pachytene cells from 3 boars of the Large White breed were analyzed twice, at a 1-year interval, using immunocytological techniques. CO rate, SC length, and MLH1 inter-foci distances varied significantly between the 3 individuals. CO rate and SC length differed significantly between the 2 sampling periods for 1 individual. However, no significant differences were observed between the 2 samples for CO distribution and inter-foci distances in the 3 boars studied.

Variation of Atmospheric Pressure
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
