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
