In mitosis, the nucleus of a cell divides to form two nuclei that are identical to the original cell. The two daughter nucleus is not only identical to each other but is also identical to the original nucleus. There are four basic phases in the cell division- a) prophase, b) metaphase, c) anaphase and d) telophase. The process of formation of identical cell in mitosis occurs in anaphase or telophase.
In the other form of cell division, i.e meiosis, 4 haploid cells are produced from diploid cells
Answer:
A polygenic trait can be described as a physical trait which is influenced by more than one gene.
The three types of selection for a polygenic trait are:
1) Directional Selection: In a directional selection, one of the phenotype is favored in an ecosystem. As a result of this favoring, the allelic frequency changes and shifts in favor of this particular trait.
2) Stabilizing selection: It is a type of natural selection in which the intermediate trait is favored. The population carries a middle trait in abundance.
3) Disruptive Selection: Disruptive trait is a type of natural selection in which the traits on the extreme sides are favored. The intermediate traits are less favored.
