These are chromosomes.
Yes, they are genetically identical because starfish reproduce asexually, and therefore the genetic makeup of each one doesn't change.
After DNA replication, when each chromosome exists as a pair of identical sister chromatids, the sister chromatids are tightly attached to each other at the centromere.
The two new cells are genetically identical to each other and the original cell.
The Centromere, use the wiki article for further reading.
The purpose of copying DNA is that, after mitosis, each daughter cell each has a complete set of DNA and is genetically identical.
So that the cell can divide into two identical daughter cells, each with its own genetically identical nucleus.
Yes, they are genetically identical because starfish reproduce asexually, and therefore the genetic makeup of each one doesn't change.
The chromatids are attached to each other at the Centromere. Hope that helps have a nice day.
After DNA replication, when each chromosome exists as a pair of identical sister chromatids, the sister chromatids are tightly attached to each other at the centromere.
In the case of identical twins, a single embryo divides into two completely separate and genetically identical embryos. Each embryo continues to grow and develop individually, but with the exact same genes as the other.On an interesting side note: Children of identical twins are genetically as closely related to their parent's identical twin as they are to their identical twin parent. Genetically, both twins are the parent of the other's children. Also, their children are genetically half-siblings.
The two new cells are genetically identical to each other and the original cell.
The daughter organism is identical to the parent in asexual reproduction.

No. Each gamete is genetically different from the other gametes and from the parent cell.
Baring a random gene mutation in a clone seed cell, yes.
The product of mitosis is two genetically identical, diploid cells - that is, each cell has the complete number of chromosomes.
