Molecular analysis of nondisjunction in mice heterozygous for a Robertsonian translocation.
A Robertsonian translocation results in a metacentric chromosome produced by the fusion of two acrocentric chromosomes. Rb heterozygous mice frequently generate aneuploid gametes and embryos, providing a good model for studying meiotic nondisjunction. We intercrossed mice heterozygous for a (7.18) Robertsonian translocation and performed molecular genotyping of 1812 embryos from 364 litters wit...
متن کاملTransmission ratio distortion in offspring of mouse heterozygous carriers of a (7.18) Robertsonian translocation.
Transmission ratio distortion (TRD) is defined as a significant departure from expected Mendelian ratios of inheritance of an allele or chromosome. TRD is observed among specific regions of the mouse and human genome and is frequently associated with chromosome rearrangements such as Robertsonian (Rb) chromosomes. We intercrossed mice heterozygous for a (7.18) Rb translocation and genotyped chr...

uniparental disomy resulting from heterozygous robertsonian translocation (13q14q) in both parents
uniparental disomy (upd) is a situation in which both members of a chromosome pair are inherited from one parent. this study has been conducted on a family with a five year-old healthy girl and a mentally retarded boy. the parents were first cousins and they both had robertsonian translocation between their long arm of chromosome 13 and 14 [45, xy t (13q14q)]. their affected son had a similar k...
