If for a species 2n = 16, then during Ist prophase and IInd prophase of meiotic division of a cell, how many tetrads and diads will be formed A) 4 and 4 B) 8 and 4 C) 8 and 8 D) 4 and 8. Explain it.

Dear Student,
The correct answer is C.If for a species 2n = 16, then during Ist prophase and IInd prophase of meiotic division of a cell, tetrads, and diads formed will be 8 and 8. This is because in prophase I of meiosis I, the homologous dyads come together and form a tetrad, so tetrads formed will be 8. In prophase II of meiosis, each dyad is composed of a pair of sister chromatids, so total tetrads and diads formed will be 8 and 8.
Regards
