How to Outsmart Your Genes
Eyes Wide Open
Have you ever wondered why you may have different color eyes than your parents or children?
Kristen, who has green eyes, and her husband, Steve, who has blue eyes, have always been curious as to why their 4-year-old daughter, Ashley, has brown eyes. "[Our theory is] the mailman," Kristen says with a laugh. "It's been a longstanding joke in our family, ever since she was born."
Pediatrician Dr. Jim Sears explains that when a baby is in the womb, he or she will have a bluish tint to their eyes because his or her eyes don't have any melanin, or color in them yet. The amount of melanin in the eyes is determined by genetics. Dr. Sears demonstrates how melanin enters the eyes and determines a baby's eye color.
Children usually develop their eye color within the first six to nine months after birth, but it can change as late as 3 years of age.
E.R. physician Dr. Travis Stork explains to the couple how their daughter can have brown eyes.
Good looks, the right chemistry, a compatible personality — finding a significant other can be complicated! But can a DNA test actually predict if couples are compatible?
Hair Today, Gone Tomorrow?
Adam, 16, has a thick head of hair, but is worried he might lose it as he gets older. "My dad is 56, and he's still got all of his hair," Adam says. "But I've been told that it depends all on your mother's side. And that's going to suck, because the entire side of my mom's family is bald. I just want to have my hair the rest of my life."
Twenty-five percent of men begin balding by age 30, and 65 percent go bald by age 60. Similarly, 25 percent of premenopausal women suffer hair loss as do 38 percent of postmenopausal women. Male pattern baldness is polygenic, which means it's caused by the genes on both the mother's and father's side, and in both men and women, pattern baldness is caused by hormones. But other factors, such as stress and excess weight, can cause hair loss due to the extra insulin in the body.
Adam underwent a genetic exam by Dr. Brandon Colby of Existence Genetics that tests if a person is more susceptible to losing their hair. The Doctors reveal his results and explain options for preventing thinning hair.

Amiya's Big Dreams
Twelve-year-old Amiya has no shortage of big dreams. In addition to opening a mobile dance studio to help fight childhood obesity among the underprivileged youth of Detroit, she also makes rounds at a hospital and hopes to go to Harvard Medical School and become an OB/GYN, just like Dr. Lisa.
To help Amiya's dream of attending Harvard become a reality, Cynosure, who makes medical equipment; TENA, a provider of bladder management products; and FloraGLO LUTEIN, an ingredient that goes into eye vitamins like Bausch & Lomb's PreserVision® with Lutein, contributed a combined $25,000 to Amiya's Scholarship Fund!
