Comparison of ELY-2.1 with blood group and ELY-1 markers in the horse.

This research article compares the distribution of ELY-2 with various blood group factors and ELY-1 in American Standardbred horses, finding that ELY-2.1 is not a product of the examined blood group loci and is not sex-linked.

Objective of the Study

• The primary goal of this study was to understand the distribution of a gene marker known as ELY-2 in the American Standardbred horses and compare this with the distribution of various blood group factors and another marker called ELY-1.

Methodology

• The researchers examined 2465 American Standardbred horses to find the distribution of ELY-2 in contrast to the blood group factors Aa, Ab, Ac, Ae, Ca, Da, Db, Dc, Dd, De, Df, Dh, Dk, Ka, Pa, Pb, X, Qa, Qc, Ua, and W.
• They also compared the distribution of ELY-2 to ELY-1 in 193 American Standardbred horses.

Major Findings

• The study found that the distribution patterns of ELY-2 were different in each case. This implies that the existence and manifestation of the ELY-2 gene marker varied between different blood groups and ELY-1.
• The research further revealed that the segregation of ELY-2.1 and factors at different blood group loci (A, C, D, K, P, Q, U and T(W)) and the ELA locus indicated that ELY-2.1 is not a product of any of these loci. This means that ELY-2.1 doesn’t arise from these categorized blood groups or the ELA locus.
• There was no segregation data available for the ELY-1 locus during this study. Therefore, no conclusions could be drawn about the relationship between ELY-1 and the other blood groups or loci.
• The article also specifies that family studies demonstrated that the ELY-2.1 gene is not sex-linked. This means that the presence of the ELY-2.1 gene does not depend on the gender of the horse.
