Pairing of homologous chromosomes in zygotene is

The pairing of homologous chromosomes during zygotene is called as:

A pair of homologous chromosomes

…………..is the pairing of homologous chromosomes during zygotene

Assertion : Synapsis is involved pairing of homologous chromosomes during zygotene of meiosis. Reason : Crossing over produces variations in the cells .

Read the statements (A) Synapsis is the pairing of homologous chromosomes during zygotene (B) Synapsis is accompanied by formation of synaptonemal complex (C) The complex formed by a pair of synapsed homologous chromosomes is called a bivalent or a tetrad (D) Thefirst two stages of prophaseI are relatively short-lived compared to the next stage that is pachytene

fill in the blanks from the followin g word:Bivalent,synapsis,tetrad,dyad,non-sister chromatids, sister chromatids,disjuction,chiasmata,anneaking. (a)The pairing of homologous chromosoms during zygotene stage of prophase of meiosis-I is termed___ (b)The two visible chromatids of a chromosome during pachytene of meiosis-I is termed___ (c)A group of four homologous chromatids (two dyads)is termed as____ (d)The two chromatids of two homologous chromosomes(bivalent)are termed as____ (e)The separation of homologous chromosomes during diplotene stage is called____
