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.
