A Note on the Somatic Y Chromosome of Reindeer (Rangifer Tarandus L.)

En anteckning om den somatiska Y-kromosomen hos ren (Rangifer tarandus L.)

Abstract

Recently a report on the reindeer chromosomes was published (Nes et al. 1965). The chromosome complement was described as consisting of 70 autosomes and a sex chromosome set of the XY-type. All autosomes were acrocentric except one pair which was submetacentric. The X was found to be submetacentric and also the largest chromosome of the complement. The Y was characterized as being the smallest acrocentric chromosome, and the authors stated that the Y chromosome could only occasionally be distinguished from the autosomes by its shorter length.

In our studies of the same species we have found a quite different appearance concerning the Y chromosome.

Sammanfattning

Kromosomkomplementet hos ren (Rangifer tarandus L.) med speciell hänsyn till Y kromosomen har beskrivits. Avvikande från tidigare observationer befanns Y vara en av de största kromosomerna i komplementet och möjlig att skilja från autosomerna. Olika möjliga orsaker till de avvikande resultaten diskuteras.
