Identify CORRECTLY matched pair.
Options
- AZygotene-Pairing of homologous chromosomes
- BPachytene-Disjunction of homologous chromosomes
- CDiakinesis-Recombination of non sister chromatids of homologous chromosomes
- DDiplotene-Nucleolus disappears
Correct answer
A. Zygotene-Pairing of homologous chromosomes
Step-by-step solution
Meiosis is divided into two stages of division - Meiosis I and II. Of the two stages, meiosis II is similar to mitosis division phase. Meiosis I is involved in the paring and recombination of the homologous chromosomes. Zygotene stage is observed in prophase-I of meiosis-I divisional phase. In this stage chromosomes start pairing together forming an association called synapsis. This pairing is observed between homologous chromosomes. This synapsis results in formation of a complex structure called synaptonemal comp
