Homologous chromosomes pair to form tetrads
WebThe pairs of replicated chromosomes are known as sister chromatids, and they remain joined at a central point called the centromere. A large structure called the meiotic spindle also forms... WebEvery cell of the multicellular offspring has copies of the original two sets of homologous chromosomes. In prophase I of meiosis, the homologous chromosomes form the tetrads. In metaphase I, these pairs line up at the midway point between the two poles of the cell to form the metaphase plate.

Web1 jun. 2009 · Homologous chromosome is when a pair of chromosomes containing the same linear gene sequences, each derived from one parent, and a tetrad is formed … Web4 sep. 2024 · During metaphase I, the tetrads move to the metaphase plate with kinetochores facing opposite poles. The homologous pairs orient themselves randomly at the equator. This event is the second mechanism that introduces variation into the gametes or spores. In each cell that undergoes meiosis, the arrangement of the tetrads is different.
Web9 sep. 2024 · Tetrads are formed in prophase I of meiosis I. Tetrad consist of two homologous chromosomes, each with two chromatids. Thus, a tetrad consists of 4 chromatids, two of which belong to each chromosome called sister chromatids which are joined at the centromere. What is a tetrad quizlet? Tetrad.
