Yes! A recent example could be babies that do not survive child birth for a certain reason, are obviously unable to pass on whatever caused them to die in the first place.
Also, once humans started to domesticate cows and drink their milk (I'm not sure why humans drink a cow's milk) their bodies evolved to continue making the enzyme to digest milk even after they were weaned off their mothers milk. Many people of Asian descend do not have this enzyme, since their culture did/does not raise as much dairy product.

The DNA polymerase reaction occurs in the ________ as incoming nucleotides are added to ________ end(s) of the growing DNA chain
nasty-shy [4]

Answer:

5' → 3' direction or 3'- hydroxyl

Explanation:

DNA replication takes place in the direction from 5' to 3' prime because the template strand is read along 3' to 5' direction and complementary strand is made in opposite direction of template strand during replication.

The new nucleotide that is added on the free 3' hydroxyl end of ribose sugar by phosphodiester bond in the new complementary strand. 3' to 5' phosphodiester linkage makes the backbone of polynucleotide.

In DNA synthesis adenine pairs with thymine with two hydrogen bonds and guanine pairs with cytosine with three hydrogen bonds. So the correct answer is 5' → 3' direction or 3'- hydroxyl.
