WebJan 23, 2024 · Cytological observation of newly laid eggs is a straightforward method to determine the cytological mechanism at present. The genetic effects obtained by the offspring from the parents change due to the different fusion methods under automixis and apomixis ( Pearcy et al., 2006; 2011b ). WebOther factors limiting genetic analysis are the small size of the Y chromosome, which makes cytogenetic definition difficult, and the absence of extensive recombination.
