Answer: The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg called ovules. The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells). The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary.
Explanation:
They both result in a particular allele rising in frequency in the population over time. They are different in that natural selection will only cause an allele to rise in frequency if that allele provides individuals with an increased relative fitness. Artificial selection can be used to cause a rise in frequency of alleles which do not provide individuals with increased relative fitness.
