The genetic structure of initial lines, parental forms and final hybrids of three home and two foreign egg chicken crosses, spread at the farms of Ukraine, with the usage of two classes of genetic markers are investigated. It is determined that the lines on the whole are consolidated, and each of them has its immunogenetic status by set and frequency of marker signs and by level of heterozygosis. It has been shown that the erythrocytic antigens A12, X14 and X62 may be the markers of the line. The essential genetic similarity between the chicken crosses of German and Czech selection is determined, that indicates their general origin.
During hybridization the increasing of the heterozygosis level to 14,25 – 30,63 % is held, what is situated on the level of more heterozygosis initial line or exceeds it considerably. The expediency of usage of the egg chicken crosses of home selection at the poultry farms of Ukraine is based.
