Title: During meiosis in a reciprocal translocation heterozygote, what are the three wa Post by: barry on Jul 16, 2012 During meiosis in a reciprocal translocation heterozygote, what are the three ways that chromosomes may segregate at anaphase I, and what are the consequences for the resulting gametes?
Title: Re: During meiosis in a reciprocal translocation heterozygote, what are the three wa Post by: duddy on Jul 17, 2012 The paracentric inversion results in two viable gametes: one with a normal chromosome and one with an inversion chromosome. Two gametes will contain fragments of a broken dicentric chromosome and will be inviable (since the acentric fragment is lost). The pericentric inversion also results in two viable gametes–one containing a normal chromosome and one containing an inversion chromosome–and two inviable gametes containing different deletion/duplication products.
