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)

The initial stage of atherosclerosis is characterized by accumulation beneath the endothelium of excessive amounts of?
kogti [31]

The initial stage of atherosclerosis is characterized by accumulation beneath the endothelium of excessive amounts of ​LDL.

  • The accumulation of lipids, cholesterol, and other chemicals in and on the artery walls is known as atherosclerosis. The accumulation is known as plaque.
  • The build-up of lipids and fibrous components in the major arteries is a hallmark of the degenerative illness known as atherosclerosis. A picture of a typical artery's anatomy can be found in Foam cells, or subendothelial accumulations of cholesterol-engorged macrophages, are the earliest lesions of atherosclerosis.
  • Nitric oxide and prostacyclin are two chemicals that are produced by your endothelium. These maintain the fluid in your blood and stop it from clotting when it shouldn't. These compounds' insufficient production is a symptom of various diseases, which raises your risk of clotting.
