Answer:

D. This is an example of directional selection in which one end of the bell curve is better adapted to its environment than the other end.

Explanation:

Directional selection is when one extreme end of a trait of a population is favored. In this scenario, the trait being discussed is the length of a giraffe's neck with the long necked giraffes having an advantage. Their ability to reach  more food increases their chances of making it to reproductive age and pass on their genes. Therefore, natural selection pressures giraffes to adapt and evolve over time to increase their chances of survival as a species.

3. In pea plants, inflated pods are dominant to constricted pods.
qwelly [4]

Answer:

Let's consider the alleles for a true- breeding inflated pod to be PP. Let's consider the alleles for the constricted pod to be pp. The punnet square for this can be shown as:

        p       p

P    Pp      Pp

P    Pp      Pp

The results from the punnet square show that there will be 100% (4:0) inflated pods offsprings produced from this cross. However, their genotype will be heterozygous.

A cross between the constricted pods can be shown as:

      p         p

p    pp      pp

p     pp     pp

The results from this cross show that the offsprings produced will be 100% constricted pod plants.
