Remember Christmas when you were a kid? My mother puts the presents out about a month early so I would have to see the gifts everyday and wait in impatient anticipation for the day when I could find out what was inside. To me being pregnant is like having to see that packaged gift everyday for nine months and have to wait to see what was inside. As with the Christmas gifts the waiting made them that much more fun but still you want to know what your baby will look like. Will he have daddy’s curly black hair or mommy’s straight blonde hair? Will have aunt May’s musical talent or will she have Uncle Jon’s athletic abilities? It’s all in the genes. Here are a few ways that your genes effect what your gift will look and act like.
Hair & Eye Color
Since lighter colored eyes like blue, green or gray are recessive genes your baby is more likely to have lighter eyes if both parents have light colored eyes. However it is possible for two brown eyed parents to have a child with blue eyes if at least two of the grandparents have blue eyes. Hair is similar, the lighter shades of hair are recessive genes so darker hair is dominant and if both parents have dark hair their baby will most likely have dark hair as well.
Your child’s height is not only influenced by genes (about 70%) but also by health, nutrition and other outside factors.(about 30%). Also whether the child is male or female plays a part since boys usually grow taller than girls. A fun way to try and determine the height that your child will grow to be add the parents’ heights together, divide by two, then add three inches for a boy or subtract three inches for a girl. Keep in mind that even though this is a pretty effective way to estimate how tall your baby will be, the height of your child can be up to five inches above or below your calculations.
Personality and Talents
Scientists have not yet been able to prove that there are specific genes that determine whether your child will be musically inclined or a mathematical, however they agree that there is a link between these things and hereditary. In one study scientists found that a person with perfect musical pitch was four times more likely to report a family member with perfect pitch and many research studies have shown that the more closely related two people are the similar their IQ’s are. Scientists consider geniuses to have a rare combination of superior genes which may require little formal schooling, like Leonardo de Vinci and William Shakespeare.
Curly hair is dominant over straight unless one of the parents is of Asian descent. (Asians have a unique straight hair gene that tends to dominate all the others.)
Even the most impatient mother knows that half the fun in raising children is the exciting twists and turns your child will make. Finding out at age 4 that your daughter has an amazing singing talent or blonde hair turning darker as your child ages are changes that make parenting a fun and unpredictable journey.
