fredd [130]

Answer:

Las unidades de Mendel se conocen ahora como GENES

Explanation:

Durante sus experimentos, Mendel demostró que las características de las plantas de guisante (por ejemplo color de la flor, color de la semilla, forma de la semilla, altura de la planta, etcétera) eran heredadas, y denominó "elementos" a las unidades portadoras de dichas características. Es decir que cada elemento o unidad discreta, era el responsable de que la planta exprese una u otra característica. Estableció que estos elementos se redistribuían independientemente uno de otro, generación tras generación. Con el paso del tiempo y el avance de las investigaciones, estas unidades o elementos fueron denominados <em>Genes</em>.

Mnenie [13.5K]

The answer is natural selection.

In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. Red and green colors of butterflies increased the chance of their <span>survival and reproduction, so these traits will pass to the next generation.</span>
