Along with 28 other courses, the GATE Ecology and Evolution exam will be given, and it will be entirely computer-based (CBT). Exams for GATE 2023 will only include objective-type test questions. There will be some multiple-choice questions (MCQ) in the question pattern, and the other quest...
Apomixis is an intriguing trait in plants that results in maternal clones through seed reproduction. Apomixis is an elusive, but potentially revolutionary, trait for plant breeding and hybrid seed production. Recent studies arguing that apomicts are not
purpurea and O. militaris individuals is more likely the result of late-acting post-mating barriers that limit crossbreeding between the hybrid and parental types or that lead to hybrid sterility. The evolution of hybrid sterility has been shown to have played an instrumental role in determining ...
ecology was first devised by ernst haeckel, a german zoologist. however, ecology has its origins in other sciences such as geology, biology, and evolution among others. q6 what is habitat ecology? habitat ecology is the type of natural environment in which a particular species of an organism ...
It is well known that asexual lineages are typically short-lived. While this observation is central to theories about the origin of sex, it still needs to be properly quantified [1]. The evolution@home results used in this work make it manageable to quantify the threat from Muller's ratchet...

Molecular evolution is usually described assuming a neutral or weakly non-neutral substitution model. Recently, new data have become available on evolution of sequence regions under a selective pressure, e.g. transcription factor binding sites. To recons

Evolution of the tenPachycladonchromosomes We have reconstructed the origin of the nine "fusion" chromosomes of the ancestralPachycladonkaryotype using the minimal number of rearrangements and assuming that the ten PC chromosomes originated from the duplicated ACK (i.e. from 16 AK chromosomes). ...
