A desert plant called Kalanchoe can reproduce, either with sexual reproduction through flowers, or asexually by budding off mini
AnnyKZ [126]

Answer:

The correct answer will be- will be called "Clones" with no genetic variation thus result in less adaptability to environment.

Explanation:

Plants can reproduce by both modes of reproduction called asexual and sexual reproduction.   The asexual mode of reproduction produces genetically similar offsprings in less period of time and thus helps in spreading of the species in minimum time as in the case of Kalanchoe.

The Kalanchoe can dominate a large area of the habitat using this mode of reproduction but at the cost of genetic variation.  

Since asexual reproduction results in Clones with same genetic material so the descendants of the plant will be less adaptive to changing the environment as asexual reproduction does not involve genes.

Vera_Pavlovna [14]
An hypothesis is a possible explanation for a set of observations or answer to a scientific question. A supposition or proposed explanation made on the   
basis of limited evidence as a starting point for further  
 investigation. 
 And practically, an hypothesis is used as the basis for further experiments, where the hypothesis is rigorously tested under varying conditions. The hypothesis that is tested and modified under different conditions may become a general 
 theory
 .The hypothesis that has the least number of variables sufficient to explain the phenomenon is preferred.
