Si una población crece mucho otra vez después de un cuello de botella con el paso del tiempo aumentará diversidad genética ¿por
sammy [17]

Answer:

los mecanismos capaces de generar diversidad actúan para incrementar la variabilidad genética en la población que sufrió el cuello de botella

Explanation:

Un cuello de botella se refiere a una reducción drástica en el tamaño de una población (por ejemplo, debido a una catástrofe natural). Un cuello de botella es un fenómeno que está asociado a la ​reducción en la variación genética y fijación de ciertos alelos en la población resultante, lo cual es causado por la deriva genética, es decir, debido al muestreo al azar de los individuos que formarán la población en la siguiente generación. Paulatinamente, los mecanismos capaces de generar variabilidad genética aumentarán nuevamente la diversidad de la población que sufrió el cuello de botella. En una población de reproducción sexual, la variación genética se genera mediante cuatro procesos diferentes: 1-mutación (es decir, la aparición de nuevos alelos debido a alteraciones en la secuencia de ADN); 2-recombinación (es decir, el intercambio de información genética entre cromátidas no hermanas durante la meiosis); 3-segregación independiente de cromosomas durante la meiosis (capaz de producir nuevas combinaciones de alelos) y 4-fertilización al azar (lo cual también incrementa el número de combinaciones entre gametos que darán lugar a un nuevo individuo).

Which statement accurately describes dark matter? It is the same as dark energy. It is well understood by scientists. It does no
kow [346]

Answer:

Dark matter does not emit electromagnetic radiation.

Explanation:

Dark matter comparative to dark energy, has various differences. You could say that dark energy is put into action on a larger scale than dark matter, which is also why dark energy makes up 74 percent of the universe. Thus, dark matter ≠ dark energy.

Scientists have a lot to learn about dark matter, so we can't claim that this subject has been well understood about scientists. In fact, it is one of the least understood parts of the universe!

_______________________________________________________

Now dark matter can be defined as particles that do not absorb, reflect, or emit light. Thus, it can't be observed by electromagnetic radiation - nor shifts in red and blue light. At the same time it does not emit electromagnetic radiation.
