Pigs (G-band), Horses (G-band, C-band, FISH), Cattle (G-band). Other species can be assessed according to need.
Pigs: 1-2% of all pigs carry a chromosome abnormality that affects their ability to reproduce. The most common type of heritable defects is a structural chromosomal abnormality known as a translocation. Globally, over 180 types of chromosome translocations have been detected in domestic swine. Of these, 45 different abnormalities have been identified in Canadian swine. Diagnosis by G-Band karyotyping will identify carriers of this abnormality.
Horses: One of the causes of reproductive failure in the horse is an abnormal number of sex chromosome known as sex chromosome aneuploidy. Mares with only one X chromosome, referred to as XO mares, have no definitive external anatomical features but exhibit poorly developed reproductive organs including uterus and ovaries and fail to exhibit estrus. Stallions with an extra X chromosome have small testis and fail to produce sperm. Definitive diagnosis for these conditions can only be obtained by G-band karyotype analysis or FISH.
Cattle: Numerous structural and sex chromosome abnormalities that interfere with fertility are known to occur in cattle. G-Band Karyotype analysis provides a definitive diagnosis.
Other: The Karyotekk team has an established track record of chromosome analysis for a variety of domestic and wild species including dog, cat, sheep, goat, bison, gaur and muskox.
