If you’re planning IVF treatment with donor eggs, you might be wondering if your baby will look like you. First of all, remember that the selection of donors is, among others, based on the physical characteristics of the recipient. It is called phenotype matching. The phenotype is a collective term for all physical characteristics, from height, weight, skin tone, hair and eye colours to facial features. If a clinic has a large pool of donors, it allows it to select donors who match the recipient’s phenotype in the best possible way. At some clinics, there is the so-called Fenomatch technology used in the donor selection process. It is Facial Matching with a scientific tool that uses biometric technology to identify facial point distances. It allows for a very accurate selection of the donor regarding concrete facial features. It analyses the donor database and returns the best possible match. Besides, when considering the resemblance between a donor-conceived child and their mum, it is necessary to mention epigenetics. In biology, epigenetics is the study of heritable phenotype changes that do not involve alterations in the DNA sequence. According to it, the phenotype can also be determined by our surrounding - and not only gene inheritance. So even if genes come from the donor, the baby may still look like the mother - the recipient. All of this is because of the influence of the environment.
