Guess my father's face based on his genetic data

[Flashball]

That is to say, try to guess his facial features (nose, jaw shape and others), pigmentation (skin color, tanning ability, eye and hair color) and his height.

It's just out of curiosity, because I don't think you can guess someone's traits just from their data, it's too complex and the classification is sometimes very subjective (Robert De Niro has a phenotype that I find among older French generations, even those from the North of France, including members of my family - could share a photo if you wish -, but this would be perceived as "atypical" by some people).

WAKE UP

Your father clusters near Maine-et-Loire so I will assume he is the typical person with four grandparents from that region of his generation.

Hair: Most likely darkish-brown to light chestnut (Fischer #4-7).

Eyes: Light brown to mixed (Martin #4-11)

Skin: Medium-fair (Von Luschan: #7-9) with moderate tanning ability (Fitzpatrick III).

Height: 1.75cm ± 2cm

Facial features: Predominantly West Alpinid so brachycephalic with round face and soft features

That is what I would guess.

Thanks.

Answers:

Yeah, in the II to III range, but with a strong tanned ability.



No, 1m67 (old) to 1m69 (young).
My father was born in 1958, he was 20 years old in 1978 and the average height was not 1m75 but close to 1m70, he measured 1m69 at 20 years old, his height was therefore in the average range for the average height of French men of the time.

Two points I would like clarification on:

Regarding height I checked this assuming your father was born in 1960s (real year 1958 not far off):
https://ourworldindata.org/grapher/a...s?country=~FRA

It indicates the average height was about 175cm for French men born during that period (1960-1970). What the average height was when your father was born should be below the average height of his generation. This means he could still be below average height for his generation.

Regarding Fitzpatrick skin type it centers around tanning ability, not skin tone. I was originally based on the description of the skins reaction to a "45-60 minute, early summer, noon sun exposure in northern latitudes" not unexposed skin color. Thus you can't have phototype I-II skin and tan very easily. If he is melanocompentant with a well-developed tanning response he would be type III or possibly even IV if he is a quick-tanner.

"First described by Thomas B. Fitzpatrick in 1972, the Fitzpatrick skin phototypes were developed based on an individual's skin color and their tendency to burn or tan when exposed to sunlight. More specifically, classification was based on a patient's responses to the following questions regarding their skin's reaction to a 45-60 minute, early summer, noon sun exposure in northern latitudes (20-45 degrees): "how painful is your sunburn?" and "how much tan will you develop in a week?" Initially enumerated as skin types I through IV to classify patients with white skin, the Fitzpatrick phototype classification scale was later modified to include types V and VI for persons with darker skin. Generally, a lower Fitzpatrick skin type classification indicates skin that burns more easily than it tans, while a higher Fitzpatrick skin type indicates the opposite (Table 1). The most common skin type in the United States is type III (48%), with types I and II comprising the second largest group (35% in total). "

Being exposed to the sun multiple times and maintaining a tan makes it difficult to classify tanning ability and actual skin color. If you asked me what my father's skin color was without a tan: probably close to type II or III
If you ask me about his tanning ability: I don't know, my father exposed himself very, very often to the sun, so he maintained his tan.

However, in real life, with my eyes and not through a camera, he still has a tan close to dark beige more than light brown, so maybe a type III (beige skin color, medium). Because one would assume that an individual with a higher tanning ability and who would maintain its tan would be darker than dark beige.

It indicates the average height was about 175cm for French men born during that period (1960-1970). What the average height was when your father was born should be below the average height of his generation.

It is very unlikely that the average height of French people was 1m75 in 1980 when it was 1m75 in 2003-2004... Now, it's 177-78.
https://fr.wikipedia.org/wiki/Taille...pom%C3%A9trie)
https://en.wikipedia.org/wiki/Averag...ght_by_country

France 2001 (+20) > 174.1 cm (5 ft 8+1⁄2 in)
France 2003-2004 (18–70) > 175.6 cm (5 ft 9 in)

I therefore maintain that the average height of French men was at least 1m70-72 in 1978-80, no higher, which means that my father was well within the low-medium range.
