With the help of one special technique,during the 26-60 hours period of incubation, from ten to ten hours, measurements were ma<strong>de</strong> uponthe dimen<strong>si</strong>ons of the primitive lane. The data suggests that earlier stages of <strong>de</strong>velopment and forthe embryos with a higher <strong>de</strong>gree of heterozigocy there is a higher <strong>de</strong>velopmental speedKEY-WORDS: heterozis, heterozicity, embryogene<strong>si</strong>sCUVTNTE CHEIE: heterozis, heterozigotie, embriogeneza
