Transgenerational epigenetic inheritance in animals has increasingly been reported in recent years. Controversies, however, surround this unconventional mode of heredity, especially in mammals, for several reasons. First, its existence itself has been qu
In doing so we clarify what evolution is. We then turn our attention to recent claims that the Modern Synthesis requires extending in order to deal with new findings in biology. At the core of these arguments are two assertions: (1) that other inheritance systems have conceptual parity with ...
Multiple mechanisms have been proposed to underlie non-DNA sequence-based inheritance and these can be either genome-associated (for example, covalent modifications of DNA and histones or transfer of small RNAs complementary to genomic sequences) or genome-independent (for example, microbiome transfer)...
To be familiar with the concepts of phenotypes, genotypes, and alleles and the application of a test cross and Punnett square as tools to understand principles of dominance and pattern of inheritance To articulate Charles Darwin’s theory of evolution and natural selection, and provide examples to...
DNA is the substance of genes, the units of inheritance that transmit information from parents to offspring. Each of us began life as a single cell stocked with DNA inherited from our parents. DNA in human cells is organized into chromosomes. ...
2011)—and regulation of genes by small RNA molecules, especially miRNAs (Kosik 2009; Hallgrímsson and Hall 2011). This now very well-characterized second inheritance system was appreciated in its infancy by John Maynard Smith, a leading twentieth century evolutionary theorist: “There is a ...

The GA trait follows Mendelian-like inheritance patterns27. Because it is highly adaptive in the presence of glucose-containing toxic baits, the GA genotype can rapidly replace glucose-accepting wild-type (WT) cockroaches28. This unique sensory polymorphism is an excellent model of rapid evolution ...
