A. Consiste en que del cruce de dos individuos de la primera generación filial (Aa) tendrá lugar una segunda generación filial en la cual reaparecerá el fenotipo y genotipo del individuo recesivo (aa), resultando lo siguiente: Aa x Aa = AA, Aa, Aa, aa. Es decir, el carácter recesivo permanecía oculto en una proporción de 1 a 4.

B. Establece que cuando se cruzan dos individuos de raza pura (homocigotos), la primera generación filial (heterocigotos), será igual entre ellos (fenotipos y genotipos) y, además, sobresaldrá el rasgo fenotípico de uno de los progenitores (genotipo dominante).

C. Dos alelos pueden generar un fenotipo intermedio cuando se produce una mezcla de los genotipos dominantes.

D. Ninguna de estas explicaciones es acorde con la segunda ley de Mendel.

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.the diverse proteins found in and attached to membranes perform many important functions.the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together.membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
