Question

can natural selection act on a trait if it has a heritibility of R2 0.1225? explain why or why not using the requiremnents of natural selection???

Answer 1

Yes , natural selection can act on a trait having heritability value i.e r2 = 0.1225.

This is firstly possible because natural selection works on heritability between the range of 0-1. Furthermore, natural selection is performed on triats that are heritable during course of change. Heritability of 0.1225 is not a major value , or all the traits could not have heritable basis of phenotypic variation but it does counts for something in terms getting acted upon during natural selection.

The requirements of natural selection-

Reproduction, variation in organisms, difference in characters ans heredity.

These are the basic requirements.

With need of heredity, it also requires acquired characteristics of the trait as well .

So it ia possible.
