What type of mutation in nucleotide 4 would produce the same amino acid?
g100num [7]
Most likely a silent mutation. Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype because the same amino acid is produced regardless of the change in the nucleotide sequence by the mutation.

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)
