What is the last to develop in a fetus?

What determines which parent the baby looks like?
However, several studies since then have shown that most infants resemble both parents equally. One study even suggests that in the first three days of life, the baby looks more like the mother—but she will tend to say the opposite, emphasizing the child’s resemblance to the father.
Why do babies look like their fathers at birth?
This behavior has its roots in evolution, the researchers suggested in the study, which was published Jan. 18 in the Journal of Health Economics. “Those fathers that perceive the baby’s resemblance to them are more certain the baby is theirs, and thus spend more time with the baby,” Polachek said.

What week is baby’s heart fully developed?
By the 10th week, the fetal heart will have developed fully. It may be possible to hear the heartbeat of an embryo from the fifth week of pregnancy. However, a scan at this stage is unlikely to show anything related to the embryo’s heartbeat.
Which side of the stomach does a baby stay?
Because your liver is on the right side of your abdomen, lying on your left side helps keep the uterus off that large organ. Sleeping on the left side also improves circulation to the heart and allows for the best blood flow to the fetus, uterus, and kidneys.
What develops first a boy or girl?
Your baby’s gender is determined at the moment of conception – when the sperm contributed a Y chromosome, which creates a boy, or an X chromosome, which creates a girl. Boys’ and girls’ genitals develop along the same path with no outward sign of gender until about nine weeks.
