2) disruptive selection
Explanation:
Disruptive selection is a type of natural selection that acts against less fit heterozygotes. The disruptive selection can be represented by a decrease in the variance of a trait. In this case, the disruptive selection eliminates the medium-sized beaks, thereby favoring the extreme phenotypes in an interbreeding population.
Answer:
To summarize, meiosis is a cellular process in which a diploid parent cell divides into four haploid daughter cells. One very important event in meiosis is crossing over, which occurs between prophase and metaphase I. Crossing over increases genetic variation. The haploid cells produced through meiosis are otherwise known as gametes.
