Is seed dispersal by ants an example of coevolution? Why or why not? Give two examples of amphibians. One of the most spectacular examples of parasitism seen in birds is A. Endoparasitism B. Ectoparasitism C.both D. Brood parasitism In what way is the insect skeleton an adaptation to the...
Compare and contrast Piaget's theory of cognitive development to Erikson's theory of psychosocial development. How are they alike? How are they different? How are Piaget and Vygotsky differences? Define the behavioral perspective of psychology and give examples. What is a...
especially useful to elucidate the role of chemical adaptation37,38,39. The evolution of cactophily inDrosophilawas a major ecological transition resulting in the ability of many species to exploit cacti with high levels of secondary metabolites. In North America, for example,D. mettleriexhibit...
hispida will allow us to uncover the genetic mechanisms behind special features of this large genus, including aerial root development, sex determination, the origin and evolution of this genus, and the codiversification of fig species with their wasp pollinators. Results Assembly and Annotation of ...
Understanding the evolution of sexual reproduction has long been at the center of evolutionary biology. Theories suggest that asexual reproduction is beneficial for the short term but costly for the long term, mainly due to accumulations of deleterious mutations and low effective population size1,2,...
thaliana, suggesting that coevolution with rhizobia has greatly shaped R gene diversity in legumes. Because R genes in legumes coevolved with rhizobia, we speculated that differences in R gene number between CMV and M. truncatula could have originated from their specificity for distinct rhizobia. ...
while integration of the minus strand would lead to thePuro+/Gfp−colonies that do not expressGFP. However, if transposon donor site resynthesis and reuse occurred, we would expect to seeGFPexpression with both of the two heteroduplex donors. For example, if the plus strand of thepHelR(mm...
For example, the high mutation rate of the mitochondrial D-loop region allows more rapid accumulation of genetic differentiation between local populations and microsatellites serve as a good complement to mitochondrial markers as they have biparental inheritance, thus their combination resulting in better ...
