Question

The point where two non sister chromatids cross over are called

Answer 1

Answer:

chiasmata

Explanation:

chiasmata is the point of contact, the physical link, between two (non-sister) chromatids belonging to homologous chromosomes. At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis.

Answer 2

Answer:

Chiasmata

Explanation:

During diplotene stage, chromatids become clear and the bivalents are now called tetrads. At places homologous chromosomes remain attached to each other. The points of attachment between non-sister chromatids of two homologous chromosomes are called chiasmata. They are the sites of previous crossing over where synaptonemal complex persists
