The evidence from ancient crops over the past decade challenges some of our most basic assumptions about the process of domestication. The emergence of crops has been viewed as a technologically progressive process in which single or multiple localized populations adapt to human environments in response to cultivation. By contrast, new genetic and archaeological evidence reveals a slow process ...
Definition. The domestication syndrome can be defined as the characteristic collection of phenotypic traits associated with the genetic change to a domesticated form of an organism from a wild progenitor form. The term “adaptation syndrome” as applied to traits automatically selected through a harvesting regime of cereals was first coined ...
Apr 2, 2014 · domestication, especially at incipient stages [11]. Out of all the species that have been identified as domesticated in the region, 27% are fruit-, nut-, and pod-producing species,
Study with Quizlet and memorize flashcards containing terms like What species were actually domesticated by humans, What is domestication syndrome?, domestic morphological traits can all be traced to the change in distribution of what embryotic cells? and more.
Aug 1, 2019 · The proponents of evolutionary model of rice domestication consider the loss/reduction of seed dispersal aids as a key syndrome trait, apart from the fixation of seed retention. We challenge this ...
Jun 9, 2010 · Jacaratia mexicana A. DC. (Caricaceae) is a tropical tree distributed throughout Mexico and Mesoamerica. Some evidence in Mexico indicates the presence of an incipient domestication process in this species. Phylogeographical analyses can potentially determine contemporary patterns of gene flow, isolation between population lineages, as well as historical processes such as population ...
Mar 9, 2011 · A second key domestication trait was the six-rowed spike, since this is able to set three times as many grains as the wild type two-rowed spike. In this review, we describe the state of knowledge regarding these two key barley domestication genes and discuss the potential applications of this knowledge in the wider context of crop improvement.
