What is sister and non-sister chromatid?

What are sister chromatids?

During anaphase-I of meiosis (A) Homologous chromosomes separate (B) Non-homologous autosomes separate (C) Sister chromatids separate (D) Non-sister chromatids separate

Exchange of genetic material between non-sister chromatids is ……………..

The points where two non-sister chromatids cross-over are called

Crossing over takes place between : (a) Two sister chromatids (b) Two non-sister chromatids (c) Three homologous chromosomes (d) Four non-homologous chromosomes

Cross-like configurations when non-sister chromatids of a bivalent come in contact during first meiotic division are

Due to the activity of recombinase enzyme, an X-shaped structure is observed between non-sister chromatids of homologous chromosomes. This is known as :-

Cross-like configurations when non-sister chromatids of a bivalent come in contact during first meiotic division are
