Are the nuclei in the daughter cells identical to the parent nucleus in mitosis? Why or why not?

Yes, because each daughter cell contains replicated genetic material, which are exact copy of one another.

Explanation:

Mitosis is a kind of cell division that results in two daughter cells that are genetically identical to the parent cell. Prior to the mitotic process, the cell undergoes DNA replication in the Interphase stage. DNA replication produces a replicated copy of the genetic material (DNA) to form two copies of each chromosome in the nucleus.

This replication gives rise to two copies of the DNA borne on replicated chromosomes called SISTER CHROMATIDS. During Anaphase stage of Mitosis, the sister chromatids separate into opposite poles and eventually into two cells after CYTOKINESIS (cytoplasmic division).

Each daughter cell now contains a nuclei that contains exact copies of genetic material without any form of recombination. Hence, each daughter cell is said to be genetically identical to the parent cell.
