Answer:
Mitosis may be defined as the process of cell division in which a single diploid parent cell divides into two daughter cells. The four stages of mitosis are prophase, metaphase, anaphase and telophase.
The chromosomes get align at metaphase plate during metaphase. Sometimes the arrangement of chromosomes takes more time and after their alignment anaphase process begins because cells has various checkpoints to maintain the proper cell division. Their improper functioning can cause diseases like cancer. The cells has proper metaphase/ anaphase transitions check point that maintains the proper cell division.

Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
