Homologous chromosome pairing is a process where maternal and paternal chromosomes of the same type are aligned, resulting in a partial exchange of genetic information through meiotic recombination.

Even the closest family separates during the day to their various jobs and schools, and kids grow up and form ... do it without genetic analysis. Paternal sisters aren't clustered around any ...

Differences between the maternal and paternal genomes were even apparent, at some level, to horse breeders in ancient times: they observed that when a female horse is mated to a male donkey ...

However, interestingly enough, research has shown that typically maternal grandparents are closer to grandchildren than paternal grandparents—though, of course, there's no hard and fast rule.
