Answer:
Mendels studies predicted inheritance in a simple manner by studying traits which were not continuous or polygenic. Hence, the patterns of Mendel's observations were simple.
But there are certain traits which are polygenic that means depending on more than one gene type and there are other traits which are continuous. These kinds of traits have complex inheritance patterns and cannot be predicted through laws of Mendel.

Answer: The correct answer is -
D) giraffes having increasingly longer necks over time.
Natural selection is an evolutionary mechanism that was proposed by Darwin.
According to this mechanism, organisms that are better capable of adapting to their changing environmental conditions, survive and increase their number through reproduction whereas other are eliminated from the population.
Example - Long neck of Giraffe, which is much elongated, lofty stature, that was beautifully adapted for browsing on the higher tree branches. This was an adaptation with slow and gradual change in the gene frequency as the lower vegetation was eaten by other animals. Due to this, giraffes had to search for other source (that was higher tree branches).
This is considered as a peculiar example of natural selection.
