Answer 2

25% is the probability that the female is a carrier for the trait. So, the correct option is (A).

What is Colourblindness?

Color blindness is defined as a reduced ability to differentiate between colors compared to the norm of normal human color vision. It is also called color vision deficiency (CVD) when a person is color blind, usually having difficulty distinguishing between certain colors such as yellow and orange, green and brown, pink and grey, or blue and green. Purple. These are typical of what is called "red-green color blindness".

The genes that can give red-green color blindness are passed on the X chromosome, although it is passed on the X chromosome, red-green color blindness is more common in males, causing males to inherit it from their mothers. There is only 1 X chromosome.

In the above case, if the mother is not colour blind but her son is color blind so, the probability for her daughter is 25%.

Thus, 25% is the probability that the female is a carrier for the trait. So, the correct option is (A).

Answers

The biopsychosocial approach is most directly concerned with assessing the relative contributions of heredity and experience to personality development (Option C)

The Biopsychosocial Approach is an interdisciplinary model which was first developed by George Engel and Jon Romano (1977).

The biopsychosocial approach is a type of model that recognizes biological (inheritance), psychological, and social (environmental) factors as well as the interactions among these factors to understand the health and illness state of an individual.

Social factors include economical, environmental, and cultural factors (e.g. work concerns and family issues).

Biological factors include both genetic and biochemical factors.

According to this approach, both mind and body determine the health of the subject.
