Question

What is chiasmata? Mention its significance.​

Answer 1

${\underline{\underline{\huge{\red{\bold{Answer}}}}}}$

During prophase of meiosis the two homologous chromosomes are seen to be joined at several points along their length. These points are called chiasmata (chiasma, a cross).

Each chiasma is the site of an exchange between chromatids. It is produced by breakage and reunion between any two of the four strands present at each site. As a result, genes  from one chromosome may swap with the genes from other chromosome leading new gene combination in the resulting chromatids.

Chiasmata : These are the points of crossing of two j non-sister chromatids during prophase of meiosis.Significance of Chiasmata :The genetic constitution of the daughter cells differs from the parent cells due to crossing over.
