" 6Tetrad is made of- "

Covering of microspores tetrad is made of :

A tetrad consists of

In Angioperms all the four microspores of tetrad are covered by a layer which is made up of :

Linear spore tetrads are formed by:

In tetrad, the number of non cross over chromatids is normally :–

Each pachytene tetrad in prophase -I is made up of (A) Four homologous chromosomes (B) Four non homologous chromosomes (c) Two homologous and two non-homologous chromosomes (D) Two homologous chromosomes

A : If a tetrad axis is passed through the unit cell of NaCl and all ions removed which are touching to tetrad axis then the formula of NaCl becomes Na_(3)Cl_(4) . R : Only one Na^(+) is removed not the Cl^(-) .
