Almost three-fourths of women are certain the fetus in their ultrasound image resembles their partner, but men are far less convinced, if at all, says 顶级国产视频 & Marshall College Psychology Professor Carlota Batres.

Her research shows this male uncertainty has an interesting reason as does female certainty.

鈥淚 had friends who would share ultrasound images and they would say, 鈥榊ou know, he has so-and-so's nose鈥� or 鈥業 think it looks like so-and-so,鈥欌�� Batres says. 鈥淚n my mind, this looks like a 20-week-old fetus, but it would make sense for mothers to have an evolutionary bias for claiming paternal resemblance.鈥�

This inspired her yearslong study with then-student and fellow researcher Amy Mullen 鈥�21, who is now a senior operations associate at a Manhattan charter school.

鈥淚 had taken numerous classes with Professor Batres, and loved every one,鈥� says Mullen, who was preceptor for her as well as teaching assistant for her upper-level psychology courses.

With this level of experience, the professor asked Mullen to help with her research.

鈥淚 was beyond excited to do so!鈥� Mullen says. 鈥淢y role was to essentially look through existing research in the field and ensure that the study we were looking to conduct hadn鈥檛 previously been done before.鈥�

When Batres became pregnant, she spoke with Lauren Trainor, a certified nurse-midwife at a local obstetrics and gynecology practice. Trainor introduced her to the ultrasound manager, Sonya Krofl.

鈥淪onya was really excited for the study and instrumental to the data collection,鈥� Batres says.

Trainor, Krofl, and Mullen became co-authors of Batres鈥� , 鈥淚nvestigating perceptions of fetal resemblance,鈥� published in March 2025.

Fetal Resemblance Research

鈥淚t would be beneficial for mothers to believe that the fetus looks like the father in order to claim paternal resemblance and get investment from the alleged father of that child,鈥� Batres says.

Why do expectant mothers think the fetus resembles their partner?

鈥淚t would be beneficial for mothers to believe that the fetus looks like the father in order to claim paternal resemblance and get investment from the alleged father of that child,鈥� Batres says.

While she made no claims about who the image in her own ultrasound looked like, Batres says when her daughter was born relatives and friends told her the infant looked like her husband.

鈥淩esearch shows that relatives, especially maternal relatives, are more likely to say the child resembles the father because, again, they're trying to claim paternal resemblance so that the father invests in the mother and the child,鈥� Batres says.

Previous studies have found that children born to fathers different from their alleged fathers range from 1% to as high as 30% with the average around 3%.

鈥淔athers can be certain now that we have DNA, but in our evolutionary past, there wasn't any way for the fathers to be certain that that was their child,鈥� Batres says. 鈥淎nd one of the ways that they gained that certainty is by having people say that the child resembles them.鈥�

For infants to actually resemble the biological father could have been dangerous.

鈥淚t wouldn't have benefited a child to resemble their actual biological father, if the child was not fathered by their alleged father,鈥� Batres says. 鈥淭hat would have increased the risk of infanticide.鈥�

Batres believes seeing resemblances in infants is done unconsciously. Photos of a child shown to strangers are more often matched to the mother.

鈥淚nfants resemble their mothers more, not their fathers, 鈥� she says.
