WebDec 20, 2012 · Established autopolyploids often have cytologically diploidized meiosis (forming primarily bivalent associations), but show polysomic inheritance at genetic markers, which is possible if the chromosomes lack pairing preferences and partner randomly at meiosis [4], [5], [14].
WebThe perceived extreme rarity of natural autopolyploids was attributed to concerns about chromosome pairing. Geneticists such as Stebbins maintained that in an autotetraploid, with every chromosome represented four times, normal chromosome pairing at meiosis would be difficult, and multivalent formation would lead to reduced fertility (Fig. 7.2). WebMar 6, 2024 · Generally, autotetraploids are believed to exhibit multivalent pairing during meiosis which disrupts normal chromosome segregations, generating less fertile progenies (Shahid et al. 2013 ). Interestingly, diploid like chromosome behavior have been observed in autotetraploids during meiosis.
