Question

Synapsis of homologous chromosomes was first observed by

• A. Winiwater
• B. Montgomery
• C. Johannsen
• D. Zickler

Answer 1

The correct option is B Montgomery

Synapsis occurs when two recombination sites are brought together by protein–protein interactions between the recombinases. In synapsis, the genes on the chromatids of the homologous chromosomes are aligned precisely with each other. Synapsis of homologous chromosome was first observed by Montgomery.

So, the correct option is 'B'.
