Is it possible for sisters to have different skin, hair colours, and hair types? E.g. hair= wavy, afro, straight, curly, black, brown, blonde, red. Skin colour: brown, peach, light brown and more.

My sister was born tow headed (she had sandy blonde hair) and her hair gradually turned reddish brown and now it’s a dark brown color and my hair color has always been an off black color.

Yes, siblings don’t have the same genes. (I’m not sure why the focus is on girls, so I’m sorry but I’m going to disregard that and keep the information general.)

Here’s how mine looks:

What does it mean to live "the 'underconsumption' life"?

Fraternal twins can look very similar or quite different, depending on the genes they inherit.

Me and my sister growing up:

We inherit half our DNA from each parent. This means siblings get a unique combination of genes from the vast pool each parent possesses.

The world of the Harry Potter series is usually considered bad worldbuilding. What are some examples of actually good worldbuilding in the books/movies?

My younger sister is much taller than me, she’s actually taller than my father. I’m shorter than both our parents. Her skin tone is very close to the singer Sade’s. While my skin tone is closer to Eva Pigford’s, at least during the spring and summer, I lose pigmentation in the fall and winter and get closer to an Alicia Key’s. Severe seasonal color loss is the bane of my existence.

My sister and I look so different from each other people thought we had different fathers growing up. lol.

People have asked her to model before for commercial ads. I’ve been asked to be a mascot outside of stores….haha.

How do I get my body in shape?

All these people are fraternal twins:

Identical twins are the exception. They develop from a single fertilized egg that splits, resulting in siblings with nearly identical DNA (though even identical twins can have slight variations).

Here’s how my sister’s natural hair texture looks:

Is it common for people to fall in love with someone else while still married? If so, why do they choose to stay in their marriage?

She’s tall, I’m incredibly short. She’s lighter in skin tone. My hair is an off black color, hers is brown. She has a slight hook nose, I have a button nose. Her eyes are a light brown color, my eyes are amber colored. Her lips are much fuller than mine are. She’s always been slim, I’ve always been curvy.

Although she’s younger, she looks older than me, her features are sharper, more defined. She looks exotic, I look like a power puff girl. I have a perpetual baby face. People think I’m the younger sister. I’m not.

My sister’s hair texture is very fluffy, airy and cotton candy like and quite fine, thin. While my hair is much thicker and closer to sheep’s wool in texture. Our curl patterns are different.

They share a significant amount of DNA, but not an identical amount. This can influence things like physical traits and susceptibility to certain diseases.

My sister has natural blonde and reddish highlights as baby hairs, framing her face. Like some hairs never changed colors for her.

Ex. Fraternal twins develop from two separate fertilized eggs. Each egg is independently released by the mother and fertilized by a separate sperm cell. Since the starting genetic material is different, the resulting twins won't be identical. They have different genes, though they will share a significant amount.

Is the Donald Trump Bible any different from a regular Bible? Has Trump altered its contents?

(When they were younger.)

Personally, my siblings all look quite different from each other. I’m Black American.

On average, siblings share around 50% of their DNA. However, this can vary slightly depending on the specific genes they inherit.

My parents force me (15yo atheist) to go to church, and there’s this thing called Small Sundays where we discuss the Bible in groups, there are questions asked about the Bible. What am I supposed to do when they ask?

So yeah, I live this. Although I think I didn’t win the genetic lottery and she did, I am grateful for my youthful appearance, at least the powers that be didn’t entirely forsake me.
