Question

BlackTom AI · Accepted Answer

When we consider X-linked inheritance from a father, the key fact is that a father passes his single X chromosome to all of his daughters, while his sons receive the Y chromosome from him and thus do not inherit his X.
Option 1: 'all of his daughters' — This aligns with the fundamental rule: every daughter gets the father's X, so they inherit that allele. The father cannot pass his X to sons, because sons receive Y from dad.
Option 2: 'half of his sons' — This is incorrect because sons get Y from their father, not his X. Therefore none of the sons receive the father's X-linked allele.
Option 3: 'all of his sons' — Also incorrect for the same reason: sons do not receive the father's X chromosome, they get the Y, so they would not inherit the X-linked allele from dad.
Option 4: 'half of his daughters' — This is misleading; each daughter gets an X chromosome from the father, so the allele on the father's X is transmitted to all daughters, not just half.
Option 5: 'all of his children' — This overstates the pattern, since sons do not receive the father's X at all; thus the allele would not be passed to all children, only to all daughters.
