heritable change造句

• If possible, then the result could be an efficient method to engineer heritable changes in genes.
• In biology, the meaning is more specific : heritable changes which accumulate over generations of a population.
• Recent findings have confirmed important examples of heritable changes that cannot be explained by direct agency of the DNA molecule.
• Extensive work in biometry seemed to indicate that continuous natural variation had distinct limits and did not represent heritable changes.
• It is, as defined by meiotically heritable changes in gene function that cannot be explained by changes in DNA sequence ."
• The permanent, heritable changes can affect either somatic cells of the organism or germ cells to be passed on to future generations.
• Recent findings have confirmed important examples of heritable changes that cannot be explained by changes to the sequence of nucleotides in the DNA . These phenomena are classed as cultural traits and symbiogenesis.
• In epigenetics, a "'paramutation "'is an interaction between two alleles at a single locus, whereby one allele induces a heritable change in the other allele.
• The classic case study of the rats who experience licking and grooming from their mothers pass this trait to their offspring shows that a mutation in the DNA sequence is not required for a heritable change.
• :I see serious problems with this article as it fails to clarify the process itself ( heritable changes in a population spread over many generations ) with methods of that process .-- talk ) 22 : 47, 8 May 2011 ( UTC)
• The Insecticide Resistance Action Committee ( IRAC ) definition of insecticide resistance is'a heritable change in the sensitivity of a pest population that is reflected in the repeated failure of a product to achieve the expected level of control when used according to the label recommendation for that pest species '.
• It seems that reversible and heritable changes can occur without a change in DNA sequence ( genotype ) and that such changes may be induced spontaneously or in response to environmental factors Lamarck's " acquired traits . " Determining which observed phenotypes are genetically inherited and which are environmentally induced remains an important and ongoing part of the study of genetics, developmental biology, and medicine.
• The NIH " Roadmap Epigenomics Project, " ongoing as of 2016, uses the following definition : " " . . . For purposes of this program, epigenetics refers to both heritable changes in gene activity and expression ( in the progeny of cells or of individuals ) and also stable, long-term alterations in the transcriptional potential of a cell that are not necessarily heritable .
