what are the modes of inheritance of sex influenced character in humans,what are the chances of baldness in F1 progeny
Answers
Some traits are carried on the sex chromosomes, X and Y. Most traits carried are present on only the X-chromosome. The Y-chromosome is smaller, and so, very few genes are located on this chromosome.
Sex traits can be categorized into three types of inheritance: sex-limited, sex-linked, and sex-influenced. Sex-limited traits are traits that are visible only within one sex. For instance, barred coloring in chickens normally is visible only in the roosters.
Sex-linked traits would be considered traits like sickle cell anemia and color blindness. They are said to be linked because more males (XY) develop these triats than females (XX). This is because the females have a second X gene to counteract the recessive trait. Thus, the trait is more likely to be visible in the male.
