What is the process of association between chromosomes called during the zygotene stage of meiosis?
Options
- ASynapsis
- BRecombination
- CCrossing over
- DChromosomal compaction
Correct answer
A. Synapsis
Step-by-step solution
This is followed by the second stage of prophase I called zygotene. During this stage chromosomes start pairing together and this process of association is called synapsis. Such paired chromosomes are called homologous chromosomes. Electron micrographs of this stage indicate that chromosome synapsis is accompanied by the formation of complex structure called synaptonemal complex. . The complex formed by a pair of synapsed homologous chromosomes is called a bivalent or a tetrad. However, these are more clearly visib
