Abstract
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.
Keywords: reciprocal translocation, low fertility, sperm analysis
Sammanfattning
Strukturella kromosomförändringar mellan tre olika autosomer hos en A.I. galt minskade grisantalet i kullar med ca. 30%. Spermanalyser samt galtens fenotyp var normala.
