摘要
We report two new Robertsonian centric fusions, designated t(4) and t(5), in New Zealand Romney sheep. Q- and G-banding studies show that sheep chromosomes 5 and 8 are fused in t(4) and that chromosomes 8 and 22 are fused in t(5). The presence of large blocks of centromeric heterochromatin in t(4) and t(5) suggests that the fusions may be of recent origin.
