The genetic material distribution in daughter cells produced by amitosis, compared to the parent cell, is generally:
Exactly identical
Significantly different
Randomly distributed with no predictable pattern
Approximately equal but not necessarily identical
Which statement BEST differentiates amitosis from other forms of nuclear division like mitosis and meiosis?
Amitosis involves DNA replication, while mitosis and meiosis do not.
Amitosis produces genetically identical daughter cells, while mitosis and meiosis produce genetically diverse cells.
Amitosis occurs in somatic cells, while mitosis and meiosis occur in germ cells.
Amitosis lacks chromosome condensation and spindle formation, unlike mitosis and meiosis.
If a cell has 2n chromosomes at the beginning of interphase, how many chromatids will it have at the end of S phase?
n
2n
3n
4n
The separation of homologous chromosomes, while still connected at chiasmata, is characteristic of which stage?
Leptotene
Zygotene
Pachytene
Diplotene
The separation of paired homologous chromosomes begins during:
Anaphase I
Anaphase II
Metaphase I
Prophase I
Which of these events does NOT occur during meiosis II?
Separation of sister chromatids
Alignment of chromosomes at the metaphase plate
DNA replication
Formation of haploid daughter cells
Which of the following events does not occur during anaphase II of meiosis?
Sister chromatids separate
Centromeres divide
Homologous chromosomes separate
Chromosomes move to opposite poles
Which of the following events does NOT occur during mitosis in somatic cells?
Chromosome condensation
Formation of the mitotic spindle
Separation of sister chromatids
Synapsis and crossing over
A somatic cell undergoing division exhibits all of the following EXCEPT:
Chromosome condensation
Spindle formation
Sister chromatid separation
Synapsis and crossing over
Which event is unique to meiosis and does NOT occur during the mitotic division of a human skin cell?
DNA replication
Cytokinesis
Crossing over
Chromosome condensation
