The answer to this question will be "Mitosis." During Mitosis the DNA cell is replicated during the cell cell cycle. Mitosis is basically cell division that equals two copied daughter cells with the same amount of chromosomes as each other during the cell cycle.
Hope this helps.
Mistakes during mitosis lead to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy. Nearly all aneuploidies that arise due to mistakes in meiosis or during early embryonic development are lethal, with the notable exception of trisomy 21 in humans.
Interphase! Most cells are in this phase and in it they copy DNA and prepare for mitosis, hope I helped
DNA supports evolution because all life on Earth carries DNA, and evolution happens only after DNA changes. These changes are called mutations and happen spontanoulsy from flawed DNA copying or from mutagens, such as X-rays or chemicals.
Phenotype = Observable/Physical characteristics.
Simple because there would be a larger gene pool, more opportunity for variation than a small population which has less of a gene pool and therefore less opportunity for variation.
