Answer:

25%

Explanation:

Una persona de fenotipo sano A puede presentar dos genotipos diferentes para la enfermedad en cuestión Aa o AA.  

Un macho de fenotipo sano puede presentar los mismos genotipos que la hembra.

Suponiendo que la hembra y el macho presentan genotipo Aa podemos obtener para cada uno dos gametas diferentes A y a. Cruzamos las gametas y obtenemos:

A a

A AA Aa

a Aa aa

only genotype aa presents the disease phenotype

En un experimento, se prueba el efecto de cambiar el pH en una reacción enzimática. ¿Cuál podría ser una variable dependiente en
stich3 [128]

Answer:

velocidad de reacción

Explanation:

Las enzimas son proteínas que catalizan reacciones, es decir, aumentan la velocidad de reacción. Si se quiere evaluar el efecto de cambiar el pH en una reacción enzimática, se debe realizar la reacción a distintos valores de pH e ir midiendo la velocidad de reacción. Por lo tanto:

pH: variable independiente

velocidad de reacción: variable dependiente

La velocidad de reacción podría medirse a través de la cantidad de producto que se forma por unidad de tiempo, o a través de la cantidad de sustrato que se consume por tiempo.

What is the definition of epistasis?
ollegr [7]

The definition of Epistasis in gene biology is Choice D: when the allele of one gene masks the phenotype of another gene

Definition:

When the phenotypic effect of alleles at one gene are masked by alleles of another gene.

In essence, a gene is said to be epistatic when its presence suppresses the effect of a gene at another locus.

It is important to know that Epistatic genes are often called inhibiting genes because of their effect on other genes which are described as hypostatic.

Additionally, there are six common types of epistasis gene interactions:

  • Dominant

  • Dominant inhibitory,

  • Duplicate dominant,

  • Duplicate recessive,

  • Polymeric gene interaction,

  • Recessive.
