WebFeb 4, 2016 · Introduction. The bipolar spindle serves as the core structure mediating proper alignment and segregation of chromosomes 1.In addition, the spindle plays an important role in defining the position of the future cleavage plane, thus controlling daughter cell size and the positioning of the daughter cells in a polarized tissue context 2 3.Proper … WebMeiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells. In prophase I of meiosis, chromosomes condense and homologous recombination takes place, leading to genetic variation through chromosomal crossover. This forms a tetrad, which is made up of four chromatids (two sister chromatids per chromosome).

WebJun 8, 2024 · Figure 13.2 B. 1: Inversion heterozygotes: When one chromosome undergoes an inversion, but the other does not, one chromosome must form an inverted loop to retain point-for-point interaction during synapsis. This inversion pairing is essential to maintaining gene alignment during meiosis and to allow for recombination.
