This shows that sexual selection is more common and intense on males than females

#Unit 8. Inheritance Biology

Broad-sense heritability range from 0 to 1.
0 =all of the phenotypic variance results from environmental variation.
1 =all of the phenotypic variance results from differences in genotype.
