Afamily has a y-linked disease that affects the father. what is the chance of a male offspring inheriting the same disease? a) 100% b)50% c)25% d)0%

The correct answer is A) 100%.

Y linked disease is the one that is caused by genes present on the Y chromosomes. Females have XX and males have XY chromosomes that determine their gender. This means that Y chromosome is only present in males and all male offsprings inherit this chromosome from their father. Whereas, female offsprings inherit X chromosome ( from each parent).

As per the question, family has Y linked disease that affects father.

Thus, there will be 100% chances of inheriting this disease by the male offspring.
