Answer:

50%

Explanation:

Olá. Primeiramente é necessário informar que perguntas em português devem ser postadas no campo "world Languagens". Isso porque esse não é o servidor basileiro e sim o servidor americano. Caso contrario, a sua pergunta pode nunca ser respondida e até mesmo excluida do site.

Em segundo lugar, para que seja possivel que você repsonda a essa pergunta você precisará preencher um Quadrado de Punnett, como mostra a figura abaixo.

Como você sabe, as mulheres possuem os cromossomos XX e os homens XY. Como a mulher apresentada na pergunta acima possui o alelo para o daltonismo, mas não apresenta daltonismo, podemos considerar que apenas um dos cromossomos dela possuem esse alelo. O alelo para o daltonismo é recessivo, sendo assim, podemos considerar que essa mulher possui os alelos XDXd. Homem com quem essa mulher se casa, não possui daltonismo, logo os alelos dele são XDY, como mostrado na figura.

Ao preencher o quadrado de Punnett, você verá que existe a possibilidade desse casal possuir duas filhas, uma delas pode possuir os alelos XDXd, igual a mãe e, portanto, ser carreadora do alelo para o daltonismo.

Sendo existe uma chance, em duas filhas desse casal ter uma filha carreadora de daltonismo. Isso é igual a 1/2, que resulta em 0,5, ou 50% de chances de ter uma filha carreadora de daltonismo.

How does the brain and the nervous system assist in times of limited body resources?
RoseWind [281]
The brain is considered as the main center of the human body. The nervous system is the system of the body that coordinates in all of the functions of the other systems. They serve as the main communication system or as the coordinator of the systems of the body. So for example if one system fails to do its function, this sends signals to the brain, then the brain sends messages to other systems to compensate of the loss. Hope this answers your question.
