- “Good genetics” in bodybuilding comes down to a couple of key factors:

Is height based on genetics?

What do daughters inherit from their fathers?
As we’ve learned, dads contribute one Y or one X chromosome to their offspring. Girls get two X chromosomes, one from Mom and one from Dad. This means that your daughter will inherit X-linked genes from her father as well as her mother.
Can a child have a higher IQ than parents?
But genetics can explain the wide range of possible IQs too because so many different genes are involved in developing and running a brain. It is possible, for example, to inherit all the higher IQ genes from each parent and leave the lower IQ ones behind. Now the child will be brighter than the parent.

It encodes a protein — tumour necrosis factor — named in 1975 because of its ability to kill cancer cells.
Who has stronger genes mother or father?
Genetically, you actually carry more of your mother’s genes than your father’s. That’s because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
