Verdadero o falso mediante el genotipo podemos determinar si existen dominancia en una característica
Murljashka [212]

Answer:

Verdadero

Explanation:

Sabemos que los caracteres dependen de los genes. Y los genes pueden presentarse en forma de alelos dominantes, o alelos recesivos. La expresión de los alelos recesivos son enmascarados o escondidos por el alelo dominante. Es decir, que si ambos alelos se encuentran juntos en un heterocigota, solo el alelo dominante se expresará.

Entonces el alelo dominante expresa la característica que resulta dominante, mientras que el alelo recesivo expresa la característica recesiva.

Genotipo:

  • Homocigota dominante ----> Expresa caracter dominante (Solo el alelo dominante esta presente)
  • Heterocigota -------------------> Expresa el caracter dominante (Ambos alelos estan presentes, pero el dominante es quien se expresa)
  • Homocigota recesivo --------> Expresa el caracter recesivo (solo alelos recesivos estan presentes)

Por ejemplo, si tenemos dos fenotipos rojo y amarillo, y sabemos que el color esta codificado por un gen dialelico llamado M. También supongamos que no sabemos qué alelo expresa qué color. Teniendo solo estos datos, no podemos decir si el rojo es el color dominante o si el amarillo lo es.

Sin embargo, si tenemos los siguientes genotipos acompañando esta información:

  • MM--> Amarillo
  • Mm--> Amarillo
  • mm --> Rojo

Recién ahora podemos deducir que el caracter dominante es el amarillo.

Why was water used to dilute the substances instead of another chemical?
BabaBlast [244]
Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7.
