If a trait in offspring does not look like the mother but looks like the father, what can be the correct reason?
Answer and explanation
Correct answer: Information inherited from the father may be dominant
The governing concept is dominance in heredity. An offspring receives genes or alleles for many traits from both parents. If the allele inherited from the father is dominant over the corresponding allele from the mother, the father-like characteristic can be expressed. This does not mean that the mother contributed nothing. Options B and C are biologically false, while food alone does not determine an inherited trait, so A is correct.
