Q. Select the event of cell cycle which shows the importance of synapsis and the formation of chiasmata
A) An increase in the variation of progeny occurs
B) The DNA on homologous chromosomes mix
C) Reciprocal exchange of chromosomal sections occurs
D) All of the above
Explanation
Synapsis is the pairing of homologous chromosomes during meiosis. While autosomes undergoes synapsis during meiosis, sex chromosomes often remain unpaired. A consequence of recombinant synapsis is to increase genetic variability within both the offsprings and population
