"event" in inglés with examples - Collocation dictionary inglés
- Its creation is the result of two separate hybridization events.
- In the late 1930s, Paul Mangelsdorf suggested that domesticated maize was the result of a hybridization event between an unknown wild maize and a species of Tripsacum, a related genus.
- Their suggestion that new species can form through a hybridization event is quite novel - biologists have often assumed that hybrid populations would die out because of hybrid sterility.
- Recently, a hybrid parthenogenetic whiptail (genus Aspidoscelis) was bred in the laboratory from a cross between an asexual and a sexual whiptail Because multiple hybridization events can occur, individual parthenogenetic whiptail species can consist of multiple independent asexual lineages.
- However, the ability to accurately discriminate between signals due to true hybridization events and what may be considered background noise is paramount to making accurate differential assessments.
- However there still was prolonged range overlap between Sequoia and Metasequoia which could have led to hybridization events that created the modern hexaploid Sequoia sempervirens.
- Most wild cottons are diploid, but a group of five species from America and Pacific islands are tetraploid, apparently due to a single hybridization event around 1.5 to 2 million years ago.
- Wagner and Whitmire attributed this to the fact that the presumed ancestral diploid at Havana Glen and those in Maryland had originated in separate hybridization events between A. platyneuron and A. rhizophyllum and that alloploidy might magnify genetic differences between the parental species.
- They argued that as the fertile population is sexually reproducing, reproductively isolated, and emerged from a common origin (in contrast to A. x ebenoides, which arises through independent hybridization events, possibly followed by vegetative propagation), it is consistent with several well-accepted biological species concepts and is deserving of recognition.
- These hybridization events can result from the introduction of non native genotypes by humans or through habitat modification, bringing previously isolated species into contact.
