Answer:
tetrads change orientation as a lineup along the center of the cell
It's genetic variation or just variation
It can impact its physical characteristics
Answer:
A) Anaphase I
Explanation:
During the Anaphase I of meiosis, the pairs of homologous chromosome split up. During this phase sister chromatids of each pair is formed and start moving towards the opposite poles. By the end of anaphase out of each pair of sister chromatids , reaches to the poles of the spindle fibre. During the metaphse of meiosis the chromosomes start their movements and arrange themselves between the poles and the equator of the spindle.
Answer:
c. A chromosomal mutation can change the total number of chromosomes in the cell.
Explanation:
A gene mutation affects a single gene, and replication error is the main cause of gene mutation. A chromosomal mutation affects one part of chromosome or full chromosome. error in meiosis is the main cause of chromosomal mutation. Both mutations are responsible for a change in DNA. A chromosomal mutation leads to the change in total number of chromosomes in the cell.
