Meiosis results in the formation of:

1. Two genetically identical diploid cells

2. Two genetically non identical diploid cells

3. Four genetically identical haploid cells

4. Four genetically non identical haploid cells

Crossing over or recombination can be defined as:

The mechanisms that contribute to the genetic variation arising from sexual reproduction include:

Identify the stage of meiotic cell division shown in the given diagram:

The beginning of diplotene is recognized by:

Meiosis results in
1. Production of gametes
2. Reduction in the number of chromosomes
3. Introduction of variation
4. All of the above 

Meiosis occurs in organism during
1. Sexual reproduction 
2. Vegetative reproduction
3. Both sexual and vegetative reproduction
4. None of these above

During anaphase I of meiosis
1. Homologous chromosomes separate 
2. Non-homologous autosomes separate
3. Sister chromatids separate
4. Non-sister chromatids separate

Meiosis is characterised by
1. Reduction division 
2. Equal division
3. Both reduction and equal division
4. None of these

A bivalent of 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
