A finch population eats seeds that vary in size. There is variation in preference of seed type, and that variation positively co

rrelates with beak size. Currently, stabilizing selection is operating on beak size with little or no directional selection. Suppose more large seeds were to become available. What is a likely result?

Answer:

If larger seed became available, directional selection will act in favor of bigger beak finch.

Explanation:

In the case that more large seeds were to become available, then directional selection will start to influence in the beak size, favoring those individuals with bigger beaks. Those individuals with shorter beaks will start to disappear as these animals won't be able to eat the larger seed.

Directional selection <em>increases the proportion of individuals with an extreme phenotypic trait,</em> in this case, large beaks.

This selection presents more frequently in those cases in which <em>interactions between living organisms and the environment</em> modify in the same direction.

mrs_skeptik [129]
<span>adding a unit to move a susceptible group enough to prevent metabolism is known as shifting.
These phenomena happen especially for liposoluble organism circulating in blood like drugs an hormones.
these molecules circulating blood can be divided into two forms : 
The free-form: which is the active part, it circulates freely in the blood, but are easily metabolised.
The bound form: it can be bound to other molecules from the organisms depending on its affinity like proteins (albumin, glycoproteins). this form is not active but is prevented from metabolism.

Competition for bounding proteins can happen between two drugs for example. If they have a different degree of affinity for proteins, then the most affine will displace the less affine from the protein and bound it, and that is call shifting</span>
