Autosomal Polymorphism via a Translocation in the Guinea Pig,iCavia porcellus/iL.

摘要

The karyotype of the guinea pig, C. porcellus L. was investigated using chromosomal preparations from various tissues of 15 animals (nine females and six males). The diploid number is 2N = 64. Only four large autosomal pairs and the X chromosome are individually identifiable. One entire X chromosome and possibly the short arms of the second X in females show late DNA replication. A polymorphism involving the short arms of the longest pair of autosomes is present in this population and this polymorphism is shown to segregate in families.
