Synaptonemal complex is visible in
1 Compound microscope
2 Simple microscope
3 Electron microscope
4 Naked eyes
Explanation:
When we observe Zygotene under the electron microscope, we see that chromosomal synapsis is accompanied by the formation of a complex structure known as synaptonemal complex.

In diploid organisms, phenomenon of crossing over is responsible for
1 Linkages between genes
2 Recombination and variation
3 Segregation between genes
4 Assortment of gene
Explanation:
Crossing over is the exchange of genetic material between two homologous chromosomes. It leads to recombination and genetic variability in a population of organisms.

Synapsis and synaptonemal complex forms in
1 Diplotene
2 Pachytene
3 Diakinesis
4 None of them
Explanation:
During Zygotene, chromosomes start pairing together and this process of association is called synapsis. Electron micrographs of this stage indicate that chromosomal synapsis is accompanied by the formation of complex structure called synaptonemal complex.

A bivalent of meiosis-I consists of
1 Two chromatids and one centromere
2 Two chromatids and two centromere
3 Four chromatids and two centromere
4 Four chromatids and four centromere
Explanation:
Bivalent is formed by pairing of two chromosomes. Thus, bivalent contains four chromatids and two centromeres.
