Exchange of genetic material between chr...

Exchange of genetic material between chromatids of homologus chromosomes during meiosis is called
or
Recombination is involved in the process of

A

Synapsis

B

Chiasmata

C

Transformation

D

Crossing over

Text Solution

Verified by Experts

The correct Answer is:
D

(d) Crossing over is a process by which chromatids of homologous exchange portions of genetic material, usually during tetrad formation of meiosis. Crossing over occurs at pachytene sub stage of prophase I of meiosis but visible at diplotene substage of prophase I.

    Which one is correct about crossing over/ genetic recombination? I. It occurs in tetrad stage. It occurs in pachytene of prophase I of meiosis I II. It occurs between non-sister chromatids of homologous chromosomes III. It is the exchange of gene.tic material between the homologous chromosomes IV. It is recombinase enzyme mediated process V. Recombination nodule of synaptonemal complex between the homologous chromosomes is the site of crossing over. VI. It causes genetic variation which is important for evolution. VII. It is also the reciprocal transfer of genes between the non homologous chromosomes
