ABSTRACT
Two commercial turkey lines: medium-heavy weight (MHW) and heavy-weight (HW) were used for a karyotype analysis and study of the frequency of chromosome abnormalities in early embryos (24 h). Among the total of 378 embryos, 40 (10.5%) had an abnormal chromosome complement consisting of 14 haploids, 20 haploid-diploid chimeras, 2 triploids and 4 diploid-tetraploid mosaics. A significantly greater frequency of heteroploid embryos was recovered from the MHW (15.4%) than from the HW line (8.0%). The discussion points to the negative effect of chromosome abnormalities on hatchability.
