s2008m [2378]

Response:

Este es un ejemplo de dominancia incompleta. Se trata de un fenómeno genético que se manifiesta cuando un gen dominante no logra expresar su totalidad en el alelo recesivo en un alelo heterocigoto dominante.

Por ende, ambos rasgos se muestran, dando lugar a una fusión de los dos alelos para los colores (blanco y rojo). El alelo rojo dominante muestra dominio parcial sobre el alelo blanco recesivo, produciendo así el alelo completamente rosado.

Según la ley mendeliana, las dos flores rojas son heterocigóticas. Por lo tanto, las flores rojas dominantes heterocigóticas deben ser R. El alelo blanco es recesivo (rr) y es enmascarado por el R rojo,

Sin embargo, al cruzar los dos alelos heterocigotos rojos:

Los fenotipos derivan en forma de

RR, (1) rojo Rr Rr (2) rosa rr (1) Blanco.

Esto ocurre porque el alelo rojo dominante no era total / completamente dominante sobre el alelo recesivo blanco en ninguno de los casos, resultando en un alelo rosa (el tercer fenotipo)

Which one of the following is the correct sequence of events that correlates to the sequence of events of a nerve impulse? 1. th
Tresset [2298]

Response:

2, 1, 4, 3.

Explanation:

The cell membrane potential can be described as the difference in electric gradient between the inside and outside of the cell. Ions play a critical role in creating this voltage difference.

Transmission of nerve impulses occurs through propagation. The cell maintains a resting membrane potential. The opening of sodium channels allows the inward movement of sodium ions, increasing the positivity of the membrane potential and causing depolarization. Subsequently, potassium ions begin to diffuse into the cell while sodium ions exit, resulting in the cell's repolarization.

Thus, the correct sequence of events is 2, 1, 4, 3.
