The actual single crossover frequency between genes A and B is 4% while the actual frequency of crossover between genes D and F is 23%. If you were using recombination frequencies to estimate the crossover frequencies of these gene pairs, in which case would you be more likely to underestimate the actual single crossover frequency

Water cycle, also called hydrologic cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff.

The hydrologic cycle describes the complex and dynamic distribution, transfer and temporary storage of water over and under the Earth's surface. As the term cycle suggests, there is a recurring succession of events (evaporation, condensation, precipitation, surface runoff, subsurface infiltration, and evapotranspiration) that keep nearly all near-surface water in an endless circulation pattern
