Phenylketonuria (PKU) is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell must have mutations to express the disease.

If we let the allele causing PKU be “p” and the normal allele be “P”, the affected individual must have “pp” combination. If both parents are heterozygous, this means the have “Pp” combination and therefore the result in their progeny will be the following:

¼: PP (25%)

¼: pp (25%)

½: Pp (50%)

This pattern will repeat itself every time they try to have a child.

Answer: From clogged arteries to infections, heart disease covers a lot of ground. It’s not just one thing, but a group of conditions that affect your heart and body in different ways. It can lead to problems like heart attacks and strokes, and it’s the most common cause of death for both men and women in the United States.

6. If you found out that a star professional football player is gay, would you be surprised?

No, being around guys most of the time would make it pretty easy to turn gay.
