The exchange of genetic material between chromatids of paired homologous chromosomes during first meiotic division is called

Question 1

(a) Transformation

(b) Chiasmata

(c) Crossing over

(d) Synapsis

Question 2

Correct option(c) Crossing over

Explanation :

In pachytene stage of prophase-I of meiosis, there is breakage and reunion of chromatids, it results in exchange of segments between non- sister chromatids of a bivalent, known as crossing over. It leads to recombination of linked genes/alleles and is a major source of continuous type of genetic variations in **** reproducing organisms.
