El pelo rizado en los perros, domina sobre el pelo liso. Calcular el porcentaje del fenotipo de los descendientes de una pareja
creativ13 [48]

Answers:

el pelo rizado en los perros domina sobre el pelo liso. una pareja de pelo rizado tuvo un cachorro de pelo tambien rizado y del que se quiere saber si es heterocigótico ¿ con que tipo de hembras tendrá que cruzarse?

4.6/5

296

El cachorro puede ser "Aa" o "AA". Se quiere saber si es "Aa". Para eso, tendría que cruzarse o con un homocigoto recesivo (aa), puesto que es el que da un 50% de probabilidades de que los hijos sean de pelo rizado.

Entonces, si se cruza con un homocigoto recesivo, la probabilidad de la descendencia debería ser 2 cachorros de pelo rizado y 2 cachorros de pelo liso.

La hembra tendría que ser de pelo liso para asegurarse de que sea homocigoto recesivo.

Si todos los cachorros salen con el pelo rizado, entonces el padre es homocigoto "AA".

Si al menos uno sale con el pelo liso, entonces el padre es heterocigoto "Aa"

A colleague has used computer modeling to design an improved enzyme. To produce this enzyme, the next step is to:___________.
Effectus [21]

Answer:

C) determine the nucleotide sequence for the improved enzyme.

Explanation:

Computational enzyme design (CED) can be defined as a bioinformatic <em>in silico </em>approach used to model, construct, and enhance enzyme catalysis. CED uses complex optimization algorithms that enable to direct evolution by using computational systems. As a further step, after the modelization of optimal enzymatic activity, bioinformaticians require to determine the nucleotide sequences which will be subsequently used to synthesize the corresponding enzymes.

A population of yeast grows in a test tube under ideal conditions until it runs out of space in the test tube. which kind of cur
MAVERICK [17]

J-shape curve

J-shape curve is a curve that shows the population density of an organisms as they increase rapidly in a logarithmic or exponential form but abruptly stops due to environmental resistance. Thus, the population rate is largely determined by the biotic potentials and size of the population. However, exponential growth produces J-shaped curve.
