Can American IVF Prevent Genetic Defects? Are Looks and IQ Inherited from Dad or Mom?

Many people have heard the sayings "boys take after their mothers, girls take after their fathers" or "like father, like son; like mother, like daughter." So, are a child's looks and IQ inherited from their father or mother? Yinye, a member of the China Human Genetic Resources Management Expert Group, points out that both parents contribute equally to their child's genes. However, there is a biological intelligence battle between the genes, so some children may resemble their father at birth and their mother a few years later, and vice versa. This kind of change is not uncommon.

Gregor Mendel, the father of modern genetics, proposed that genes determine traits, and parents' genes significantly influence a child's height, weight, personality, and IQ. Dominant genes such as high nose bridges, big eyes, double eyelids, long eyelashes, skin color, and large earlobes are easily passed on to children. For instance, if one parent has these dominant gene traits, the likelihood of their children inheriting them is high. Skin color follows a "first multiply then average" natural law: if one parent is fair-skinned and the other dark-skinned, the child's skin color is usually intermediate. Additionally, traits like acne, hair loss, obesity, and height also have high genetic probabilities but are greatly influenced by the environment.

So, what about IQ? Many reports suggest that intelligence is primarily concentrated on the X chromosome. A boy's intelligence tends to come from his mother, while a daughter's intelligence is influenced by both parents. Yinye, however, states that a child's IQ is more influenced by education. Both parents often believe that any lack of intelligence comes from the other side, making it hard to determine which parent the child resembles in intelligence. American neurobiologist Dr. Lise Eliot has proposed that the golden period for a child's brain development is from 0 to 6 years old. The education and nurturing provided by parents during this time are crucial.

However, with environmental degradation, increasing trends of late marriage and childbirth, and various pressures, the rate of birth defects is rising. China is one of the countries with a high incidence of birth defects, with 800,000 to 1.2 million children born with defects each year, accounting for about 5% of all births. Therefore, whether or not there is a family history of genetic diseases, especially for older couples, chromosome screening is recommended.

Dr. Nathan Zhang, an expert in the field of assisted reproduction, a PhD from the University of Pennsylvania School of Medicine, and founder of IVF USA, suggests that those with a family history of genetic diseases, genetic carriers, and older couples at high risk of birth defects should consider American IVF-PGT technology. In most countries and regions, IVF technology involves transferring embryos with only 6-8 cells, making it impossible to determine if the embryo has chromosomal or genetic defects. However, American IVF-PGT technology can culture embryos to the fifth day to form a blastocyst with over 100 cells. Before implantation, these blastocysts are screened using PGD/PGS to check for over 200 genetic diseases, ensuring the health of the transplanted embryos. This method is closer to the natural state of embryo implantation, thus increasing the success rate.
