PHENOTYPIC TRAITS

these are the characteristics or traits that can be observed and measured. it is the expression of genes in a way that they are readily observable.

the ability to roll one's tongue is a dominant phenotypic trait while if one cannot, he/she has inherited recessive form of the allele, thereby showing the recessive phenotypic trait.

Consider a continuous phenotypic trait with an initial average value of 5. In the next generation, the average value of the trait is 7. The narrow-sense heritability of the trait is 0.5. Assume that selection accounts for all of the evolution of this trait. What was the selection differential? The answer is 4.
