Identify three types of natural selection for a polygenic trait.
kaheart [24]

Answer:

A polygenic trait can be described as a physical trait which is influenced by more than one gene.

The three types of selection for a polygenic trait are:

1) Directional Selection: In a directional selection, one of the phenotype is favored in an ecosystem. As a result of this favoring, the allelic frequency changes and shifts in favor of this particular trait.

2) Stabilizing selection: It is a type of natural selection in which the intermediate trait is favored. The population carries a middle trait in abundance.

3) Disruptive Selection: Disruptive trait is a type of natural selection in which the traits on the extreme sides are favored. The intermediate traits are less favored.

Si todas las células del organismo reaccionaran cómo lo hacen las del higado, se esperaría que ?
Marat540 [252]

Answer:

Si todas las células reaccionaran como el hígado, cada una tendría la capacidad de producir proteínas, colesterol, almacenamiento y liberación de glucosa, procesaría la producción de hemoglobina y amoníaco en la urea, purificaría las drogas y los desechos, regularía la coagulación, produciría los factores necesarios en la respuesta inmune e intervendría en la formación de bilirrubina, principalmente, sin embargo, debe tenerse en cuenta que una de las funciones principales es el suministro de energía, si cada célula tuviera reservas de glucosa por momentos de estrés, rápida regeneración celular ante las lesiones, las células no tendrían la capacidad de tener una adaptación específica de sus funciones y los procesos que son básicos para el funcionamiento humano serían destruidos, como un eritrocito cuya función es el transporte de oxígeno, no lo haría ser viable si se dedica a producir glucosa porque su estructura debería adaptarse a otra y sin oxígeno el cuerpo no vive, por lo que sería caótico que los sistemas sí no tienen una adaptación específica y son las mismas, aunque las reacciones hepáticas son vitales, requiere el apoyo de otros órganos con diferentes funciones para que estas tengan lugar, es de resaltar que el hígado tiene una respuesta rápida y efectiva ante el estrés, busca recursos para poder mantener funcionando muchos sistemas, si las células se adaptarán con la misma rapidez, se evitaría la aparición de muchas enfermedades.
