As male children get older some begin to closely resemble their fathers and have no resemblance to their mothers, which statement explains this observations

The question is incomplete as it does not have the options which are:

1) Several sperm fertilized the egg, so the fertilized  egg contained more genes from their father.

 (2) More genes are inherited from the sperm

cell of their father than from the egg cell of their mother, so most traits will be like those of their father.

 (3) More genes from their father are expressed  in traits that can be seen, and more genes from their mother are expressed in traits that cannot be seen, such as blood type or  enzyme function.

 (4) Genes from their father are stronger than genes from their mother, so the genes from  their mother are not expressed.

(3) More genes from their father are expressed  in traits that can be seen, and more genes from their mother are expressed in traits that cannot be seen, such as blood type or  enzyme function.

Explanation:

In the given question, the traits of a father are expressed in older age as compared to a younger age.

This could be explained by the fact that the genes from the father are expressed in the trait which is observed during older age but the genes of the mother are expressed in the traits which are not observed during the older age.

This is not true that the genes of a father are more dominant then the mother and the genes of the only mother are transferred.

Thus, the selected option is correct.

the answer would be..
