reciprocal crosses造句

• The reciprocal cross produces sterile F1 males and no female progeny.
• Variations include half diallels with and without parents, omitting reciprocal crosses.
• Reciprocal crosses are included within the same grex.
• Thus, reciprocal crosses between normal and dwarf specimens may give rather different results.
• The reciprocal crosses made between normal sized chickens with Bantams revealed that Bantams carry one or several sex-linked dominant genes that reduce body size.
• This can happen when the mating that produces descendants only allows one of the two species to function as the female progenitor and the other as the male, while the reciprocal cross does not occur.
• An intriguing study surveying the transcriptome of murine brain tissues revealed over 1300 imprinted gene loci ( approximately 10-fold more than previously reported ) by RNA-sequencing from F1 hybrids resulting from reciprocal crosses.
• Given that the trait of interest is either autosomal or sex-linked and follows by either complete dominance or incomplete dominance, a reciprocal cross following two generations will determine the mode of inheritance of the trait.
• The most obvious application is an experiment that contains all parents and their offspring, with or without reciprocal crosses, preferably replicated without bias, enabling estimation of all appropriate means, variances and covariances, together with their standard errors.
• Similar results are observed in mosquitos of the Culex genus, but the differences are seen between reciprocal crosses, from which it is concluded that the same effect occurs in the interaction between the genes of the cell nucleus ( inherited from both parents ) as occurs in the genes of the cytoplasmic organelles which are inherited solely from the female progenitor through the cytoplasm of the ovule.
