Ο γιος σου μοιάζει πολύ σε εσένα, ενώ η κόρη σου μοιάζει περισσότερο στον μπαμπά της.

Greek uses the definite article much more often than English does.

So:

• ο γιος σου = literally the son your
• η κόρη σου = literally the daughter your

But in natural English, both simply mean your son and your daughter.

With family members, Greek normally keeps the article in sentences like this. So ο γιος σου is the standard way to say your son, not a strange extra word.

Because Greek possessive pronouns of this type usually come after the noun.

So:

• ο γιος σου = your son
• η κόρη σου = your daughter

This is the normal Greek pattern:

• το σπίτι μου = my house
• η φίλη της = her friend

English says your son. Greek usually says the son your.

If you want strong emphasis, Greek can use a different structure, such as ο δικός σου γιος, but that is more emphatic, like your own son or your son, not someone else’s.

Μοιάζει is the 3rd person singular form of μοιάζω.

In this sentence, it means:

• resembles
• takes after
• looks like

So:

• Ο γιος σου μοιάζει πολύ σε εσένα = Your son resembles you a lot
• Η κόρη σου μοιάζει περισσότερο στον μπαμπά της = Your daughter resembles her dad more

With people, especially family members, μοιάζω is very commonly used to talk about resemblance.

Because μοιάζω is commonly used with σε + person when talking about resemblance.

So Greek says:

• μοιάζω σε κάποιον = I resemble someone / I take after someone

That is why the sentence has:

• σε εσένα = to you / you

Even though English says resemble you without a preposition, Greek often uses σε here.

Also, εσένα is the full pronoun form used after a preposition. You cannot use σου after σε. After a preposition, Greek needs the full form:

• σε εσένα
• more commonly in everyday speech: σε σένα

Yes, but it is small.

• σε σένα is the more everyday, common spoken form
• σε εσένα is fuller and can sound a bit more careful or emphatic

Both mean to you / you in this kind of sentence.

So in ordinary speech, many people would say:

• Ο γιος σου μοιάζει πολύ σε σένα

The version with σε εσένα is absolutely correct; it just sounds a little fuller.

Because στον is the contracted form of σε + τον.

So:

• σε + τον = στον

This is very common in Greek:

• στον = to the for masculine nouns
• στην = to the for feminine nouns
• στο = to the for neuter nouns

So:

• στον μπαμπά της = to her dad

This contraction is standard and expected.

Because the noun changes form here.

The dictionary form is:

• ο μπαμπάς = dad

But after σε / στον, Greek uses the accusative form:

• τον μπαμπά
• στον μπαμπά

So:

• ο μπαμπάς = nominative, used for the subject
• τον μπαμπά = accusative, used after σε / στον

This is why the sentence says στον μπαμπά της, not στον μπαμπάς της.

Της means her.

Here it refers to η κόρη σου — the daughter.

So:

• στον μπαμπά της = to her dad

Greek is viewing the father from the daughter’s point of view: her dad.

Even if the listener is one of the parents, Greek very naturally says her dad rather than repeating your husband or something similar.

Here ενώ means whereas or while in a contrastive sense.

It connects two contrasting ideas:

• The son resembles you a lot
• whereas the daughter resembles her dad more

So in this sentence, ενώ does not mainly mean two things are happening at the same time. It is introducing a contrast.

Because they are doing different jobs.

• πολύ = a lot / very much
• περισσότερο = more

So:

• μοιάζει πολύ σε εσένα = resembles you a lot
• μοιάζει περισσότερο στον μπαμπά της = resembles her dad more

In the second clause, the comparison is understood from context. Greek does not need to spell out more than you if it is already obvious.

If you wanted to make it fully explicit, you could say something like:

• μοιάζει περισσότερο στον μπαμπά της απ’ ό,τι σε εσένα

That means she resembles her dad more than you.

You may hear both, but σε is especially natural when talking about taking after a person, particularly a family member.

So this sentence:

• μοιάζει σε εσένα
• μοιάζει στον μπαμπά της

sounds very natural for family resemblance.

With με, Greek often expresses general similarity or appearance:

• μοιάζει με τον πατέρα της = she looks like her father / she is similar to her father

In everyday speech, the two patterns can overlap, but in this family context, σε is a very normal choice.

Yes. Μπαμπάς is the everyday, affectionate word for dad.

A more formal or neutral word is:

• πατέρας = father

So a more formal version of that part would be:

• στον πατέρα της

Both are correct. The sentence uses μπαμπά because it sounds warm and natural in everyday speech.
