The study is from 23andme and is using imputation for most of it (statistical methods to infer unobserved genotypes ).

"Analysing the phenotypic data, the researchers also looked at associations between being a morning person and other conditions such as body mass index, insomnia, depression and sleep duration. They found that a morning person is much less likely to have insomnia, less likely to require eight hours of sleep and less likely to suffer from depression than individuals who reported being “night owls.” Taking into account of the effect of age and sex, morning persons are also more likely to have lower BMI, according to the research. The researchers also found that morning persons were less likely to be on the extreme ends of body mass index, meaning they were less likely to be obese as well as less likely to be underweight."
There's also this:
"shows clustering along time zones — especially among the states in the mountain time zone — Colorado, New Mexico, Wyoming, and Montana. And, according to 23andMe scientist Kasia Bryc who did the analysis, some of the states with the highest proportion of morning people also tend to have older populations. But there are many anomalies, making it difficult to draw conclusions. At the same time the map illustrates that as with most traits, it’s not just genetics that plays a role."
The states mentioned have higher percentages of early risers. It's also higher in far northeastern states like Maine, and states like New Jersey, Rhode Island, etc. are also pretty high for it. I don't know if ancestry plays a role in this, but I think the age of the population would also be a factor.
The only snp on the V3 platform is this one:

I'm TT. When I was younger and more carefree I would fall asleep the instant my head hit the pillow and I never needed an alarm clock...I was up by 6:30 the latest every morning. My father was the same. I could never nap or sleep during the day even if I'd been out till 3 or 4 AM. I always envied people who could do that. My mother must have had the other allele. She wandered around half the night and then had to struggle to get up, although she did. Most nights I bet she only got about four or five hours sleep. She was also thin as a greyhound her whole life, so there goes that theory.
