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.
Answer:
is the genetic material that makes up living things, and folic acid plays an important role in the formation of DNA. Jon wants to study the effect of folic acid on DNA formation in microbes. Which statement accurately describe the variables in this study?
Folic acid is the variable as it determines how DNA is formed, DNA contains the genetic materials that is passed across to offspring
Explanation:
The best answer is: introducing exotic species into
<span>
new environments. This can be actually bad, as new species can actually reduce the biodiversity in the environments to which they're introduced</span> , such when cats hunt indigenous birds.
I was a bit thinking about the last option too: making sure local people benefit from conservation efforts.
This is not one of the classical goals of the conservation efforts, but since the previous one is definitely correct, i don't this one is. (it's not that it's not a goal, but it isn't a main focus)
The option that is an example of the "ethical dilemma" of creating and destroying human embryos is option A: Some people..."believe an embryo has the same moral standing as a human being?"
<h3>What moral dilemmas do embryonic stem cells present?</h3>
The infinite differentiation potential of iPSCs, which can be used for human cloning and pose a risk for the creation of human embryos and human-animal chimeras, is the center of the current ethical debates surrounding stem cell-based therapies.
However, due to the fact that it involves the killing of human embryos, hESC research is morally and politically contentious. The controversy over abortion has a strong connection to the issue of when human existence begins in the United States.

By using ratios. You get a punnet square and then get the ratio or even the percentage.
