Question

which statement about inheritance is true?
male offspring will always have an x - linked genetic disease if the mom is a carrier
fathers always determine the gender of the offspring in humans.

Explanation:

1. Analyze the first option (not fully visible, but likely incorrect as inheritance rules are more defined).
2. Analyze the second option: For X - linked recessive diseases, a carrier mother (X^A X^a) has a 50% chance of passing the affected allele to her son (who gets X from mom and Y from dad). So sons don't always get the disease, so this statement is false.
3. Analyze the third option: Human females have XX chromosomes and males have XY. The father donates either an X or a Y chromosome. If he donates X, the offspring is female (XX); if he donates Y, the offspring is male (XY). So fathers determine the gender. This statement is true.

Answer:

Fathers always determine the gender of the offspring in humans.
