How many chromatids make up a tetrad
Did you know?
WebA tetrad is an association of two identical chromosomes (4 sister chromatids), kept together by at least one DNA crossover. The two identical or homologous chromosomes link together during cell division, particularly during the zygotene stage of meiotic prophase I, to produce the bivalent or tetrad structure. WebSep 17, 2024 · Tetrads are formed in prophase-I of meiosis I. A tetrad consists of two homologous chromosomes, each with two chromatids. Thus, it consists of 4 chromatids. …

As the combination of two chromosomes (a pair) containing 4 chromatids (two original, two replicated) is also known as either a tetrad or a bivalent, we can also say that a tetrad has two chromosomes and four chromatids. Tetrás in Greek means four, while bi relates to two.
