The right answer is Karyotype

The karyotype corresponds to the representation of chromosomes of the nucleus of a cell seen under microscopy or microphotography, after ordering in pairs according to size. Such a procedure makes it possible to highlight chromosomal abnormalities, such as trisomies, or to define certain characteristics of the individual, such as genetic sex from the sex chromosomes.

Si se aparean especies diferentes como por ejemplo el cruce entre caballos y burros; podemos afirmar que si llegan a tener desce
White raven [17]

Answer:

El híbrido va a ser esteril.

Explanation:

En la cruza entre dos especies distintas, cuando ocurre, existen distintos mecanismos de aislamiento reproductivo, que son barreras que inhiben o interrumpen el flujo génico entre especies distintas. Es decir que no habrá exito reproductivo de estas cruzas. Se trata de caracteres biológicos propios de cada especie que previenen la reproducción con otras especies.

Estos mecanismos de aislamiento reproductivo pueden ser precigóticos o postcigóticos.  

  1.Pre-copulatorios o pre-cigóticos:

  • Ecológico o por aislamiento de hábitat;
  • Estacional o temporal;
  • Sexual o etológico;
  • Mecánico;
  • Por incompatibilidad de gametas.  

  2. Post-copulatorios o cigóticos:

  • Inviabilidad del híbrido;
  • Esterilidad del híbrido;
  • Híbrido con viabilidad o fertilidad disminuido;
  • Interacciones citoplasmáticas.

La mula es producto de la cruza entre dos especies distintas: una yegua (Equus ferus caballus) y un burro (Equus africanus asinus). Es un ejemplo de la accion de mecanismo poscigótico, en el cual se forma un híbrido viable esteril. Este ejemplar puede nacer, crecer y sobrevivir, pero que no puede producir gametas funcionales, por lo cual no puede reproducirse.

Which statement BEST characterizes the general relationship between air pressure and elevation?
Ad libitum [116K]

Both have an inverse relationship.


Explanation:

The two have an inverse relationship, that is, when elevation increases, atmospheric pressure decreases.

This is due to the amount of air on top of you at your current elevation.

At lower elevations, you have more air above you, and thus more pressure.

At higher elevations, you have less air above you, and thus less pressure.


At high elevation food takes longer time too cook due to low pressure, so at high altitude pressure cooker is used to cook food.


OK, :)
