Question

which structure forms during meiosis, consisting of four chromatids of each chromosome? triad tetrad dyad monad

Explanation:

During meiosis, homologous chromosomes pair up. Each chromosome has two sister chromatids. So when two homologous chromosomes pair (one from each parent), there are a total of four chromatids. This structure is called a tetrad. A triad is not a standard term in this context. A dyad refers to a pair (like a chromosome after meiosis I in some cases with two chromatids). A monad is a single - chromatid chromosome (after meiosis II).

Answer:

tetrad
