Question

будетлибудетлипроходитьестественныйотборв однородной популяции, например у дочерних растений, вегетативно разможившихся злаков ???.Пожалуйста...

Answer 1

если все экземпляры аналогичны,то нет

Answer 2

От чего у меня такое ощущение, что будь они хоть 100%-е копии естественный отбор будет. Почему? Потому что если они попадут в очень плохие условия борьба за пищу будет не на жизнь, а на смерть. 

 

Но это лишь моё скромное мнение, поскольку я не фан биологии.

Answer 3

Natural Selection in Homogeneous Plant Populations

In a homogeneous population of asexual plants, such as vegetatively propagated cereals, natural selection can still occur, although the mechanisms and factors involved may differ from those in sexually reproducing populations.

Natural Selection in Asexual Plant Populations: In a homogeneous population of vegetatively propagated plants, natural selection can still take place. While traditional natural selection based on genetic diversity may not apply in the same way as in sexually reproducing populations, other factors such as environmental pressures, competition, and random mutations can still drive the process of natural selection [[1]].

Environmental Pressures and Adaptation: Even in a genetically uniform population, environmental pressures can lead to the survival and proliferation of certain traits that confer advantages in specific conditions. For example, in a population of vegetatively propagated cereals, plants with traits that make them more resistant to prevalent diseases or better adapted to local environmental conditions may have a higher chance of survival and reproduction, leading to the propagation of these advantageous traits [[2]].

Competition and Resource Utilization: Competition for resources within a homogeneous population can also drive natural selection. Plants with traits that allow them to more efficiently utilize available resources, such as water or nutrients, may outcompete others and have a higher reproductive success, leading to the prevalence of these advantageous traits in the population [[3]].

Random Mutations and Genetic Variation: Although asexual reproduction does not generate genetic diversity through recombination, random mutations can still occur and contribute to genetic variation within the population. While the rate of genetic variation may be lower compared to sexually reproducing populations, these mutations can still introduce new traits that undergo natural selection based on their fitness in the given environment [[4]].

In conclusion, natural selection can indeed occur in homogeneous populations of vegetatively propagated plants, driven by factors such as environmental pressures, competition, and random mutations, even in the absence of traditional genetic diversity resulting from sexual reproduction.
