Abstract

Temporal parameters of expression of the aspartate aminotransferase gene Aat-1 parental alleles were studied in early development of intergeneric reciprocal F1 hybrids of the bream, roach, and blue bream. When the first Aat-1 expression was timed to the early stages (late blastula-gastrula), the gene parental alleles were activated asynchronously according to the maternal types (blue bream × roach hybrids). When the first Aat-1 expression was timed to later stages (yolk sac resorption), the parental alleles were activated synchronously (bream × roach, roach × bream, and roach × blue bream hybrids). The pattern of activation of embryonic genes is determined by the maternal environment and the influence of allele interactions is not excluded: Aatf/Aat-sl (bream × roach, roach × bream, and roach × blue bream) and Aat-sl/Aat-med (blue bream × roach).
