Cuál corresponde al tipo de crecimiento vegetativo en el que hojas subterráneas pueden dar origen a plantas idénticas
katen-ka-za [31]

Answer:

Propagación vegetativa

Explanation:

La propagación vegetativa es un tipo de reproducción asexual vegetal a partir de células, tejidos u órganos (por ejemplo, hojas, tallos y raíces) capaces de dar origen a organismos genéticamente idénticos mediante mitosis. Este mecanismo ha sido explotado en mejoramiento genético y en agronomía a fin de reproducir plantas con características fenotípicas deseadas a partir de un número reducido de células somáticas. Las regiones de la planta capaces de dar origen a un nuevo organismos se conocen como propágulos, los cuales pueden ser rizomas (a partir de raíces), tubérculos (tallos), estolones (brote laterales), etc. Diferentes tipos de suculentas tales como, por ejemplo, <em>Sedum morganianum</em>, Sedum<em> rubrotinctum</em>, <em>Kalanchoe daigremontiana</em> y <em>Graptosedum</em> o “California Sunset” se reproducen vegetativamente mediante propágulos foliares.

In _____________ selection, individuals with both extreme forms of a trait are at a selective advantage.
jok3333 [9.3K]

Answer:

disruptive/diversifying selection  

Explanation:

Disruptive (also known as diversifying) selection is a type of natural selection where extreme phenotypic values are more favored rather than intermediate phenotypes. The disruptive selection favors the survivance and reproduction of organisms with extreme phenotypic traits, and in turn impairs the reproduction of organisms with intermediate traits, thereby changing the allele frequencies in the population in order to favor extreme values. An example of disruptive selection is the beak size of Galapagos finches, where extreme phenotypes of this trait have shown to be adaptive according to the type of food found in each island.
