Meiosis in diploid organisms results in:
1. production of gametes
2. reduction in the number of chromosomes
3. introduction of variation
4. All of the above
At which stage of meiosis does the genetic constitution of gametes is finally decided
1. Metaphase-I
2. Anaphase-II
3. Metaphase-ll
4. Anaphase-I
Meiosis occursin organisms during
1. sexual reproduction
2. vegetative reproduction
3. Both (a) and (b)
4. None of these
During Anaphase-I of meiosis
1. homologous chromosomes separate
2. non-homologous autosomes separate
3. sister chromatids separate
4. non-sister chromatids separate
A bivalent meiosis-I consists of
1. two chromatids and one centromere
2. two chromatids and two centromeres
3. four chromatids and two centromeres
4. four chromatids and four centromeres
Identify the wrong statement about meiosis
1. | Pairing of homologous chromosomes |
2. | Four haploid cells are formed |
3. | At the end of meiosis the number of chromosomes are reduced to half |
4. | Two cycle of DNA replication occurs |
