A structural rearrangement involving three autosomes, numbers 2, 4 and 15, was transmitted from an A.I. boar of Finnish Landrace breed to its offspring. The boar was used extensively for breeding work; its phenotype was normal, and it had normal sexual functions and semen characteristics. However, because of the small size of its litters, blood samples were taken from the offspring for chromosome analysis.
一种涉及2号、4号和15号三条常染色体的结构重排,从一头芬兰长白猪品种的人工授精公猪遗传给了它的后代。这头公猪被广泛用于育种工作;它的表型正常,性功能和精液特征也正常。然而,由于其产仔数少,于是从其后代中采集血样进行染色体分析。
