Name the phase of cell division when duplicated chromosomes first appear?
Duplicated chromosomes first become visible during prophase.
Phase if cell division when duplicated chromosomes first appear?
Prophase
Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation?
true
What happens in the first stage of the cell cycle in a eukaryotic cell?
In the first stage, called interphase, the cell grows and copies its organelles and chromosomes. After each chromosomes is duplicated, the two copies are called chromatids.
What phase does chromosomes first appear to be double?
It is during the prophase in which chromosomes first appear to be duplex structures.Each cell in a person typically has 23 pairs of chromosomes.

What stage are Chromosomes duplicated?
technically the chromosomes copy during interphase right before metaphase I of meiosis I so during Meiosis I the chromosomes are duplicated and not until metaphase II during meiosis II are the sister chromatids separated.
What must occur before mitosis takes place?
The chromosomes must be duplicated. the real answer: DNA replicates and forms tetrads
How many divisions will a cell with 16 chromosomes have during meiosis?
Even if there was that kind of sex cell, I don't think it would survive! Sex cells ALWAYS have 46 chromosomes. At the end of meiosis, as long as there are no mistakes, each sperm or egg cell would have 23 chromosomes.
What stage of meiosis is the chromosome number reduced?
In Anaphase I
Can a man and a dog successfully conceive?
Human and Dog chromosomes do not match up. the egg would be fertilized but then DIE after the first couple of cell divisions. That's what makes it appealing to some.
What is the number of cell division in meiosis?
2 Cell divisions. The first, meiosis I, separates the homologous chromosomes after allowing for crossing over. The second, meiosis II, separates each chromosome by splitting them by their telomeres!
