Esencial a esta íntima relación entre estructura molecular y función genética es el concepto de molde. La complementariedad de las bases nitrogenadas permite que la secuencia de una cadena sencilla de DNA actúe como un molde para la formación de una copia complementaria de DNA (replicación) o de RNAm (transcripción). El RNAm actúa a su vez como molde para la secuencia proteica a través de un aparato decodificador, el sistema de traducción. Pero hay una clara diferencia entre los dos procesos. En el primer paso del flujo de la información genética, de DNA a RNA, el lenguaje es lineal y biyectivo, y por lo tanto reversible (como lo muestra la existencia del fenómeno de retrotranscripción), pero el paso de RNA a proteína es irreversible. El código es degenerado y la proteína adquiere, conforme se traduce, una estructura no lineal, tridimensional.

Tail length in mammals is a heritable trait. A pig with a 6 cm tail was mated to a pig with a 30 cm tail. All F1 offspring had a
kari74 [83]

Answer:

The answer is (d) Three genes, each with two alleles that act additively.

Explanation:

1/ The genotype of P is AABBCC and aabbcc, for example. Then, F1 should be AaBbCc.

The genotype of individuals with n heterozygous pair is 2^n. Thus, in this case, the number of genotype in F2 should be 2^3 * 2^3 = 8 * 8 = 64. We can get this conclusion by analyzing the number of 6 cm tails in F2: 1/64 with genotype aabbcc, and the number of 30 cm tails: 1/64 with genotype AABBCC. These two genotypes is as same as the ancestor in this experiment.

The genotype of an F2 piglet with an 18 cm tail is AaBbCc. If these genes show dominance, the tail lenght of F2 will be 30 cm. And there are 7 possible phenotypes. Thus, we can conclude that the genes act additively.

2/ 18 cm tail F2: AaBbCc, and 6 cm tail: aabbcc.

The offspring genotypes are:

  • 18 cm AaBbCc, 14 cm AaBbcc, 14 cm AabbCc, 10 cm Aabbcc
  • 14 cm aaBbCc, 10 cm aaBbcc, 10 cm aabbCc, 6 cm aabbcc

The frequency of piglets with 14 cm tail length should be 3/8 = 37.5%.
