NEET Questions / Botany / Cell Cycle and Cell Division / Meiosis
What is the purpose of meiosis?
Growth and repair of tissues
Produce gametes for sexual reproduction
Asexual reproduction
Maintain chromosome number in somatic cells
During meiosis, crossing over occurs between:
Sister chromatids of homologous chromosomes
Non-sister chromatids of non-homologous chromosomes
Sister chromatids of non-homologous chromosomes
Non-sister chromatids of homologous chromosomes
What is the primary outcome of meiosis II?
Separation of homologous chromosomes
DNA replication
Crossing over
Separation of sister chromatids
During which phase of meiosis does the centromere split, allowing sister chromatids to separate?
Metaphase I
Anaphase I
Telophase I
Anaphase II
In which stage of meiosis do the sister chromatids become independent chromosomes due to the splitting of the centromere?
Prophase II
Anaphase II
Metaphase II
Telophase II
The separation of sister chromatids during meiosis is a crucial event. This separation is a direct consequence of which of the following?
Formation of the chiasmata
Alignment of homologous chromosomes at the metaphase plate
Division of the centromere
Synapsis of homologous chromosomes
In which stage of meiosis I does terminalization of chiasmata become a prominent characteristic?
Pachytene
Zygotene
Diplotene
Diakinesis
During which phase of meiosis I do the chiasmata shift towards the ends of the chromosome arms?
Anaphase I
Metaphase I
Prophase I
Telophase I
Which of the following events marks the beginning of the diplotene stage of prophase I in meiosis?
Formation of the synaptonemal complex
Synapsis of homologous chromosomes
Crossing over between non-sister chromatids
Dissolution of the synaptonemal complex
The separation of homologous chromosomes, while still connected at chiasmata, is characteristic of which stage?
Leptotene
Zygotene
Pachytene
Diplotene
