In multivalent polyploids, simultaneous pairings among homologous chromosomes at meiosis create a exclusive cytological phenomenondouble reduction. Fisher’s classifications for different gamete development modes through the polysomic inheritance of the multivalent polyploid. By applying a two-stage hierarchical EM algorithm, we produced a closed-form option for estimating the frequencies of dual decrease through the estimation of gamete… Continue reading In multivalent polyploids, simultaneous pairings among homologous chromosomes at meiosis create
