La miopia es un caracter bastante comun en la especie humana. Un matrimonio en el que ambos conyugues poseen vision normal, tienen dos hijos, uni con una vision normal y el otro con miopia. Teniendi en cuenta el fenotipo de todos los miembros de la familia ¿quenpodrias deducir del gen que controla la miopia? ¿ que genotipo podrias asignsr a cada individuo?

Answers

Answer 1

Answer:

El gen que controla la miopia es dialelico, autosómicoEl alelo dominante M expresa visión normal, El alelo recesivo m expresa  miopia, Los padres con visión normal serían heterocigotas, Mm.Tendrían un hijo con visión normal homocigota dominante MM o Heterocigota Mm   Tendrían otro hijo homocigota recesivo con miopia, mm.

Explanation:

Datos disponibles:

Ambos padres poseen visión normalUno de los hijos tiene visión normalEl otro hijo tiene miopia

Podríamos establecer que M es el alelo dominante, mientras que m es el alelo recesivo.

A partir de la información brindada, podríamos suponer que:

Opción 1:

La miopia es un caracter expresado por un gen dominante. Si este fuera el caso, entonces al menos uno de los padres debería tener miopia para poder heredarle al hijo el alelo dominante para expresar el caracter. Si este fuera el caso, los posibles genotipos de los padres serían:

Parental)  Mm   x   mm (al menos uno de los padres con miopia)

F1) 1/2 Mm (Hijo miope)

    1/2 mm (Hijo con visión normal)

Pero en este caso, los dos padres tienen visión normal, entonces si el gen dominante expresa la miopia, los genotipos de los padres serian homocigotas recesivos, mm. Si ambos padres son homocigotas recesivos, no podrían heredarle a ningun hijo el alelo de la miopia. En este caso, la cruza sería:

Parental) mm    x    mm

F1) 100% mm (todos los hijos con visión normal)

Sin embargo, para el ejemplo planteado, los dos padres tienen visión normal, uno de los hijos tiene visión normal y el otro tiene miopia, lo que nos conduce a la segunda opción.

Opción 2:

La miopia es un caracter heredado por un gen recesivo, m. Mientras que la visión normal es heredada por un gen dominante, M. Entonces, si este fuera el caso, para que ambos padres con visión normal, tengan un hijo homocigota recesivo para el caracter, entonces ambos padres deberian ser heterocigotos. Su hijo miope heredaría un alelo recesivo de cada padre y expresaría el defecto. El genotipo de las personas con miopía sería entonces homocigota recesivo. Esta cruza sería de la siguiente manera:

Parental) Mm    x    Mm  (Ambos padres heterocigotas)

Gametos) M   m     M     m

Cuadro de Punnet)

                M             m

     M       MM         Mm

     m       Mm         mm

F1) 3/4 o 75% de probabilidad de tener un hijo con visión normal

    1/4 o 25% de probabilidades de tener un hijo miope.

Entonces, podemos concluir que:

El gen que controla la miopia es dialelico, autosómicoEl alelo dominante M expresa visión normal, El alelo recesivo m expresa  miopia, Los padres con visión normal serían heterocigotas, Mm.Tendrían un hijo con visión normal homocigota dominante MM o Heterocigota Mm   Tendrían otro hijo homocigota recesivo con miopia, mm.

List two examples of how chemical or nuclear energy can be transformed. ​

Answers

1. The sun transforms nuclear energy into heat and light energy.

2. Chemical reaction is a chemical substance that can be transformed to other forms of energy. As an example, when a fuel is burned the chemical energy of molecular oxygen is converted to heat, and the same is the case with digestion of food metabolized in a biological organism.

Answer:

Explanation:

for chemical energy is can be transformed in several ways since it is potential energy it can be transformed into kinetic energy  or into electrolysis because  batterys  contains energy within.

Which statement best compares the amount of fossil fuels formed each year to the amount used each year? The amount of fossil fuels formed is exactly the same as the amount used. The amount of fossil fuels formed is approximately the same as the amount used. The amount of fossil fuels formed is much less than the amount used. The amount of fossil fuels formed is greater than the amount used.

Answers

Answer:

The amount of fossil fuels formed is much less than the amount used.

Explanation:

Fossil fuels, which include petroleum, coal, natural gas etc are an example of non-renewable sources of energy. They are termed non-renewable because they are sources that gets exhausted quickly without replenishment.

One of the characteristics of non-renewable sources of energy is that they get exhausted faster than they can be produced. Hence, regarding fossil fuels as an example of non-renewable source of energy, this means that the amount of fossil fuels formed is much less than the amount used.

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. For more evaporation, the area that surrounds the surface of the water must be less humid i.e. it should not already be concentrated have the water vapors. For the evaporation we need to increase the temperature of the molecules of water on the surface, which is caused by the Sunlight.

Answers

Answer: c. Our higher brain tells us it is inappropriate and incorrect symbolism

Explanation:

We wouldn't we wear formal attire or use forks when eating soup because our higher brain tells us it is inappropriate and incorrect symbolism.

The higher brain helps us to interpret vision, emotions, touch, speech, reasoning etc. Since eating soup with forks isn't appropriate, this will be detected by the higher brain. The higher brain simply performs intellectual functions.

What is one advantage of urbanization?

Answers

Answer:

Advantages of Urbanization

Urban residents in many parts of the world tend to live longer than do rural residents, and have lower infant mortality and fertility rates. Cities provide better access to medical care, family planning, education, and social services. Recycling is more economically feasible.

Ventajas de la urbanización:

Crecimiento sostenido. El crecimiento de las ciudades va acompañado de una mayor demanda de servicios básicos y de bienes de consumo, lo cual genera un mercado mayor a satisfacer.

Concentración poblacional. Las ciudades son ámbitos más controlables por los Estados y con mayor facilidad de cobertura de redes de servicio o de distribución, dado que la población se concentra en algunos kilómetros a la redonda.

Complejización laboral. El mercado de empleo en la ciudad es mucho más diverso y variado que en las zonas rurales, permitiendo así el desarrollo y complejización de las actividades industriales, comerciales y de servicios.
