In homo sapiens(humans), males are the heterogametic sex meaning their sex chromosomes are not the same(=XY) while females are homogametic(=XX).
Sex linked traits or x linked traits are traits whose genes are present on the X chromosome. So if there is a recessive mutation in those genes, males will express that recessive trait. Basically males express everything that’s on their X chromosome because they only have 1, but females have 2 which helps “hide” the mutation and to not express the particular recessive trait.
That is why sex linked traits are more evident in males in the population and an example of that would be colorblindness.

The answer is the superposition principle.
The superposition principle states that the oldest rocks occurs on the <span>bottom of an undisturbed rock sequence.

It could be very useful in determination of relative age of fossils.</span>
