A few things that I found interesting about the heritability concept were that it is expressed as a percentage. For example, if the heritability of a trait is 40 percent, that means that less than half of the differences among individuals in their trait are due to differences in their genes. In other words, the 60 percent is from differences in their environment. Another example is height; the heritability of height in adults is between 70 and 80 percent. On the other hand, religious affiliation is almost entirely due to environment, meaning there are no heritable traits.
As I have reached a stage where I feel like I am done growing (height wise) I have noticed that I am taller than my mom, but shorter than my dad, and falling right in between the both of them so the heritability is 50/50. An example of environment is religious affiliation, I was raised as a Christian, as was my mother, but it is still considered an environmental trait, not a heritable trait. Another environment trait is my choice of food, my mom loves salad, she will eat it everyday, however, I do not like salad at all, and therefore the trait of eating salad was not inherited.
One question that I have always wondered is why do some people think that I look Mexican, Latino, Puerto Rican etc. but I am mixed with black and white. I am not sure whether it is hereditary or a coincidence.
