Is bad sleep hereditary?

I've had 3 nights f not the best sleep waking up a few times in the night which isn't very normal for me. My dad isn't a good sleeper but he can function on a few hours a night. I need around 7-8 hours. No one else in my family is a bad sleeper though. Just wondering if it's possible for me to be like my father? I love my sleep and hate bad nights.
