Allele X codes for a cooperative behavior among full siblings. Recipients of this behavior receive a benefit of 7 fitness units and the behavior costs the donor 3 fitness units. Use Hamilton's rule to determine whether allele X will spread in the populati

What will be an ideal response?


ANS:
Hamilton's rule rb – c > 0; in this example r = 0.5, b = 7, c = 3; substituting the values produces 0.5 x 7 – 3 = 0.5 > 0; the allele will spread
