WebTrisomic mouse models provide an in vivo genetic platform for examining the gene-phenotype relationship, including the influence of allelic variants, on DS-like phenotypes. … Web3. (1 point) Nondisjunction can result in gametes that carry an extra copy of a chromosome, and at fertilization this can result in a zygote with a trisomy. In some cases, the zygote somehow eliminates one of the three copies of the trisomic chromosome, restoring euploidy. It's really not understood how this happens.
