Absolute dating methods determine how much time has passed since rocks formed by measuring the radioactive decay of isotopes or the effects of radiation on the crystal structure of minerals. Paleomagnetism measures the ancient orientation of the Earth's magnetic field to help determine the age of rocks.

JulsSmile [24]

To observe the first generation offspring of the cross between the flowers c and a. the most likely genotype of flower c is its color.

<h3>What is genetic probability?</h3>
