Vedclass · Answer

(A) Chiasmata are the $X$-shaped structures formed between non-sister chromatids of homologous chromosomes during the process of crossing over in the $Pachytene$ stage of $Meiosis-I$.The number of chiasmata is directly proportional to the length of the chromosomes. Longer chromosomes have a higher probability of undergoing multiple crossover events,leading to a greater number of chiasmata compared to shorter chromosomes.

List-$I$ (Phase of meiosis)	List-$II$ (Event that occurs)
$1$. Prophase $I$	Crossing over occurs
$2$. Metaphase $I$	Sister chromatids migrate to opposite poles
$3$. Anaphase $I$	Homologous chromosomes line up at the equator in pairs
