Grandparents are the parents of a person's father or mother – paternal or maternal. Every sexually-reproducing creature who is not a genetic chimera has a maximum of four genetic grandparents, eight genetic great-grandparents, sixteen genetic great-great-grandparents, etc., although the numbers will be lower in cases of pedigree collapse. In the history of modern humanity, around 30,000 years ago, the number of modern humans who lived to be grandparents increased exponentially. It is not known for certain what spurred this increase in longevity, but it is generally believed that a key consequence of three generations being alive together was the preservation of information which could otherwise have been lost; an example of this important information might have been where to find water in times of drought.

In cases where parents are unwilling or unable to provide adequate care for their children (e.g., death of the parents), grandparents often take on the role of primary caregivers. Even when this is not the case, and particularly in traditional cultures, grandparents often have a direct and clear role in relation to the raising, care and nurture of children. Grandparents are second-degree relatives and share 25% genetic overlap.

Grandma is a female grandparent.

Mike Biggs

Officer Michael "Mike" Biggs (Billy Gardell), is the lead male protagonist of the series. He is introduced in the first episode as a Chicago police officer with weight issues who attends a meeting of Overeaters Anonymous. It is here that he meets Molly Flynn. After Molly asks Mike to come and speak to her class at the school where she works, they begin dating in the second episode. Mike is regularly accompanied by his best friend, Carl McMillan, his partner on the police force, whom he joins for breakfast to chat about the state of their lives at a cafe where their waiter is always Samuel, an African immigrant who likes to make fun of Mike's weight. Mike and Molly got engaged in the season 1 finale, are married in the season 2 finale, and are still trying to conceive their first child as of the Season 4 premiere. In Season 5, though, Mike finds out that Molly went back on birth control without telling him due to the pain and frustration of two years when she was unable to conceive a child, and they resolve to pursue avenues like adoption as they still love each other and want to raise kids.
