Webb8 apr. 2024 · The pairing of homologous chromosomes is a vital step for meiosis because the rightness of the homologous separation depends on the process. This event occurs in prophase I of the cell division. WebbNondisjunction can occur during either meiosis I or meiosis II. If nondisjunction occurs during meiosis I, then all of the resulting gametes will have an abnormal number of chromosomes (one gamete will have an extra chromosome and the other will be missing a …

Homologous Chromosomes: Definition & Examples

WebbThe bivalent chromosome consists of paired homologous chromosomes. Sister chromatids of each chromosome are joined at the centromere. Chromatids of homologous chromosomes are joined at chiasmata, which are (more...) At metaphaseI, the bivalent chromosomesalign on the spindle. WebbSynapsed, paired homologous chromosomes are termed bivalent —indicating two joined or synapsed chromosomes—or tetrad —representing the four separate chromatids in the bivalent structure. Importantly, bivalent chromosomes in pachytene undergo an exchange of chromatid material in a process called recombination or crossing-over. cuties wipes reviews
