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). … WebAfter the inversion loop is formed during synapsis, crossing over occurs between the two chromosomes. Abnormal chromosomes are produced after the crossover structures are resolved. Pericentric inversion. In a pericentric inversion, the centromere lies within the inverted region of the chromosome. ...
