Question

Synapsis occurs between:

• A. Two homologous chromosomes
• B. A male and a female gamete
• C. mRNA and ribosomes
• D. Spindle fibres and centromere

Answer 1

The correct option is A Two homologous chromosomes

Synapsis is the pairing of homologous chromosomes (a pair of chromosomes which have the same genes. Among the members of a homologous pair, one comes from the paternal gamete and the other from the maternal gamete) that occurs during meiosis. It allows matching up of homologous pairs prior to their segregation, and the possible chromosomal crossover between them. Synapsis takes place during prophase I of meiosis.
