Identify the correct matched pair.
(1) Segregation-Metaphase ll
(2) Significance of meiosis-production of genetically similar cells
(3) Exchange of genetic material- DIakinesis
(4) Anaphase ll of meiosis-Centromeric division
What is the correct sequence of the steps given here ? Also work out the process depicted in the steps.
(i) Homologous chromosomes move toward opposite poles of the cell; chromatids do not separate
(ii) Chromosomes gather together at the two poles of the cell and the nucleare membranes reform
(iii) Homologous chromosomes pair and exchange segments
(iv) Homologous chromosomes align on a central plate
(v) The haploid cells separate completely
(1) The correct sequence is and the process is meiosis-I
(2) The correct sequence is and the process is mitosis
(3) The correct sequence is and the process is meiosis-I
(4) the correct sequence is and the process is mitosis
During meiosis, the sister chromatids separate during:
(1) Anaphase II
(2) Anaphase I
(3) The S phase
(4) Synapsis
The total DNA content of each daughter cell is reduced during meiosis because:
1. | Chromosomes do not replicate during the interphase preceding meiosis I |
2. | Chromosomes do not replicate between meiosis I and II |
3. | Half of the chromosomes from each gamete are lost during fertilization |
4. | Chromosome arms are lost during crossing over |
Which of the following is not true for sister chromatids?
(1) They arise by replication during S phase
(2) They segregate from each other during each mitotic anaphase
(3) The usually contain identical versions of the same genetic information
(4) They segregate from each other during meiosis I
