Answer:

Explanation:

This statement is incorrect because the Cytoskeleton is not unique to animal cells. Vegetal cells also have a cytoskeleton.

Answer:

The cytoskeleton is a unique structure of all eukaryotic cells, which are all cells that have true nucleus. Thus we can say that the cytoskeleton is present in cells animal, plant cells and any other eukaryotic cell.

Explanation:

The cytoskeleton is a complex network of fibers found in eukaryotic cells that allows them to adopt various shapes and perform the most varied movements. It is composed of three types of molecular structures: the microtubules, the actin microfilaments or filaments and the intermediate filaments.

The cytoskeleton therefore has several functions, which can be summarized as follows:

  • Ensures shape and mechanical support of the cell;
  • Promotes movement of cytoplasmic organelles and vesicles;
  • Important in cellular contraction;
  • Enables amoeboid movements.

Importantly, the cytoskeleton, because it ensures the movement of vesicles and can manipulate the plasma membrane, enables processes such as endocytosis and exocytosis to occur.

En el hombre el color negro de los ojos “A” domina sobre el color azul “a” Una pareja en la que el hombre tiene los ojos negros
umka21 [38]

Las respuestas a estas preguntas son:

a) Genotipo del padre Aa (ojos negros)

b) Cruzamiento: Aa (padre) x aa (madre)

c) Frecuencias genotípicas esperadas: 1/2 Aa; 1/2 aa  

En genética, dominancia completa se refiere al proceso  de herencia en la cual un individuo heterocigota, es decir, el individuo que presenta dos alelos diferentes para el mismo gen, presenta el mismo fenotipo que un individuo homo-cigota para el alelo dominante (el alelo dominante es aquel que enmascara la expresión del alelo recesivo en individuos heterocigotas).

En este caso, el carácter 'color de ojos' presenta un patrón de herencia monogénica, donde el alelo 'A' dominante codifica para el rasgo fenotípico ojos negros, mientras que el alelo 'a' recesivo codifica para el rasgo fenotípico ojos azules.  

En el ejemplo, la pareja tuvo progenie en la cual uno de los hijos presenta el rasgo recesivo ojos claros, con lo cual el padre debe ser heterocigota y poseer un alelo recesivo 'a'; mientras que la madre expresa el fenotipo recesivo y por lo tanto su genotipo es 'aa'. En consecuencia, el cruzamiento de un padre heterozigota 'Aa' con una madre homo-cigota recesivo 'aa' producirá una descendencia con una frecuencia genotípica esperada de 1/2 (50%) de hijos con ojos 'color negro' de genotipo Aa y 1/2 (50%) de hijos con ojos 'color celelste' de genotipo aa >>

Cruzamiento: Aa (padre) x aa (madre)

Gametos padre: 1/2 A; 1/2 a

Gametos madre: 100% a

Cuadro de Punett (combinaciones gaméticas):

                  A           a

a               Aa          aa

a               Aa          aa

En consecuencia,  este cruzamiento producirá 50% individuos ojos color negro (genotipo Aa) y 50% individuos con ojos color celelste (genotipo aa)
