How we create your report

BabyPeek uses advanced technology to analyze well-known genetic factors that determine what traits a baby will most likely have. Much like a weather report, results are calculated as probabilities.

Eye color
Genetic changes in two genes, HERC2 and OCA2, are strongly associated with eye color. That’s because these two genes actually work together to control melanin production, particularly in the iris.
Red hair
The most well-studied gene that affects whether or not hair is red is called MC1R. This gene helps the body make eumelanin. Changes in the gene make it not as good at making eumelanin, leading to more pheomelanin in the hair–this makes hair red!
Curly hair
The most well-studied gene that affects hair texture is called TCHH. This gene helps the body make proteins in the hair strand called keratins. TCHH affects how keratin forms, which determines how hair grows–either straight or curly.
Light or dark hair
In addition to the MC1R gene, which is the most important for red hair, BabyPeek looks at other genes that determine how much eumelanin the body produces, so we can determine what shade hair will likely be on a scale from blonde (low eumelanin) to black (high eumelanin).
Hair thickness
The EDAR gene is directly involved in the development of hair follicles. People with specific changes in EDAR have thicker hair strands than those that don’t. By looking at whether or not your baby has this change, we can predict how likely they are to have thick hair!
Freckles
The MC1R gene helps melanocytes naturally produce high levels of melanin. When there are lower levels of natural melanin in the skin, sun exposure is more likely to lead to concentrated spots of melanin–AKA, freckles!
Cilantro
One genetic change affects how likely olfactory receptors are to detect the aldehydes (“smell chemicals”) in cilantro that also smell like soap, determining how likely your baby is to like or dislike cilantro!
Bitter taste
Some people can taste the bitter PTC chemical while others cannot. While the foods we eat do not contain PTC, bitter foods have been found to contain similar chemicals. People who are not sensitive to these bitter flavors may enjoy these foods more.
Asparagus odor
Scientists believe the OR2M7 gene affects the ability to smell asparagus. This gene gives the body instructions on how to make a specific microscopic structure in the nose that latches on to and senses certain chemicals in the air, like sulfur or citrus.
Sweet taste
The gene TAS1R3 encodes taste receptors and affects a person’s ability to detect sucrose, one of the main chemicals that makes foods taste sweet. By looking at changes to this gene, we can determine if your baby is more or less sensitive to sweet flavors.
Sweet vs. salty
The FGF21 gene produces a hormone that regulates our metabolism and how our body responds to sugar. FGF21 may affect how much of this hormone is produced when we eat sugar, determining how likely we are to seek a sweet or salty snack.
Teeth
The EDA gene is linked to when a baby’s first teeth emerge. Babies with particular changes in this gene are more likely to have their first teeth emerge earlier (5-7 months of age) than others (6-8+ months of age).

This was so fun to be able to see what my babies traits will most likely be! It will be interesting to compare the results after the baby is born. Definitely recommend BabyPeek as an added reveal moment for a fun memory during your pregnancy.

This made me tear up! Thank you!

Gabrielle

BabyPeek Parent

What a fun test! Much of the BabyPeek traits are similar to my other three children I have. So, a very accurate test, really impressed!

Cassandra

BabyPeek Parent

BabyPeek is just too cool. I can’t wait to see how accurate the results for traits are. So far the gender was correct according to my ultra sound!

Kathryn

BabyPeek Parent

I love that I can get a sneak peek before baby comes, it definitely helps with the anticipation!

Avery

BabyPeek Parent

I absolutely loved it - it really is a sneak peek at what your baby is going to be like.

Jessica

BabyPeek Parent

I would suggest this to anyone! I love to have an idea of my babies traits to come.

Jaycee

BabyPeek Parent

Every trait that was given was exactly what my other kids looked like as well! I think this is super accurate and I think first time parents would love this!
