Imagine we are selecting porcupines to make them pricklier. The heritability of prickliness is 0.75. Average prickliness before selection is 100 (standard deviation is also 100). The average prickliness of the porcupines who produce the next generation is 108. What will the prickliness of the next generation be?

a) 100

b) 108

c) 106
