Color blindness, also known as color vision deficiency, is a condition characterized by the inability vĩ đại perceive certain colors or distinguish between them.

Inheritance Patterns:

1. X-Linked Inheritance (Most Common): The majority of color blindness cases follow an X-linked inheritance pattern. This means that the genes responsible for color vision are located on the X chromosome. Since males have one X chromosome and females have two, males are more commonly affected by color blindness. If a male inherits a mutated color vision ren from his mother, he is likely vĩ đại be color blind. Females, on the other hand, can be carriers of the condition if they have one mutated ren but may not show symptoms unless they have two mutated genes.
2. Autosomal Inheritance: In rare cases, color blindness can be inherited in an autosomal pattern, where the genes responsible for color vision are located on autosomal chromosomes (non-sex chromosomes). With autosomal inheritance, both males and females have an equal chance of being affected by color blindness.

If an individual had good prodromal functioning, it means they experienced fewer or less severe prodromal symptoms, which can be a positive indicator for a better recovery outcome.
B) Schizophrenia initially triggered by stress: Stress can play a role in triggering or exacerbating symptoms of schizophrenia. If schizophrenia was initially triggered by stress, it implies that identifying and managing stressors can potentially improve the recovery process.
C) Schizophrenia developing in early life: Early intervention and treatment are crucial for improving outcomes in schizophrenia. If schizophrenia develops in early life and is identified and treated promptly, it can contribute vĩ đại a better prognosis and recovery.
In contrast, an abrupt beginning vĩ đại the disorder (option D) is not specifically linked vĩ đại a fuller recovery.
