Answer:
<em>The correct option is D) cytokinesis</em>
Explanation:
Mitosis can be described as a process in a cell replicates to form two identical copies of itself.
Cytokinesis can be described as the last stage of cell division for both prokaryotes and eukaryotes. During this stage, the cytoplasm eventually divides and the cell splits into two with equal portions of cytoplasm in each side. Although the mechanism of cytokinesis is different for both plants and animals yet it is the final stage for both the cell type in which the cytoplasm splits.
Answer:
Genes coding for proteins involved in chiasma formation.
Explanation:
Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.
Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.
