WebDuring prophase I, the pairs of homologous chromosomes come together to form a tetrad or bivalent, which contains four chromatids. Recombination can occur between any two … WebDuring pachytene of meiosis-I, the paired chromosomes of each bivalent condense and become more distinct. Further, sister chromatids in each chromosome become distinct due to the appearance of a longitudinal furrow. Thus, each bivalent clearly appears as a tetrad consisting of four chromatids. Final Answer: During, meiosis-I, the bivalent ...
