How is it possible when NO ONE in your family not even 5 generations back had curley hair but you end up with it??

same thing with me!

lol I look to much like my mum and my relatives

It’s totally possible and totally normal. It could be hormones (your mum’s when she was carrying you), or genetic from hundreds of years ago.

Hormones can cause curles. Inadequit ammounts of hormones can cause straightning, thinning hair.

My dad and all his family were black hair blue eyes and my mom and all her family were blond hair blue eyes, i’m green eyes with brown hair and the only one on both sides to be that way haha so I understand.

hahah You know what my dads side also has black thin hair but with brown eyes and my mums side had thick blond hair and blue eyes im brunette with green eyes… and thick curly hair…. lol

Curly hair is actually produced due to the shape of your hair follicles. Those with circular follicles have straight hair, those with flat follicles will have curly hair, & if they are oval you’ll get wavy hair. Those with curly or wavy hair have “faulty” follicles. (I have curly hair, & consider myself fortunate, not faulty LOL!). You probably have what they call a throw back gene, one which hasn’t appeared in your family for a long time.

Your family most likely carries a recessive gene for curly hair. Every time your ancestors had a child with someone their spouse did not have the recessive gene but it was carried down through the generations. Finally, your parents met and they both carried the recessive gene for curly hair so now you have curly hair.

But wouldnt it effect the first born?? I’m the 4th child

I quote the following: “… The answer to your question may lie in the way that hair-type genes are inherited. First, a review of some basic genetics stuff. For most genes, you have two copies of each gene that you inherited from your mother and father. For most “traditional” genes, there is a dominant and recessive version. This all has to do with gene expression and phenotype, or what you actually end up looking like. If at least one dominant version of the gene is present, it will be expressed regardless of what the other is. The only way the recessive version will be expressed is if the dominant version isn’t present. This holds true for some simple traits like whether earlobes are attached or not, where the free earlobe allele is dominant (noted as “E”) and the attached (noted as “e”)allele is recessive. So if at least one of your parents had free earlobes (Ee or EE), you’ll have free earlobes. EDIT: if both you’re parent have free ear lobes you can still get attached ear lobes in the case that there heterozygous dominate. because if both parent are Ee then you have 1/4 chance of getting ee. So why don’t you see your hair-type in your parents or grandparents? Well, hair-type doesn’t follow the nice and simple pattern of inheritance. Hair-type follows a type of inheritance pattern known as “incomplete dominance”. Like the earlobe gene, there are two versions of the hair-type gene, curly (noted as C) and straight (noted as s). The incomplete dominance refers to the fact that if you have one of each version of the gene, you get a mix of the two or, in this case, wavy hair. So for hair type, CC gives curly, Cs gives wavy and ss gives straight hair. Without a better family history, all I can tell you is that it is possible that the curly version of the gene was carried by both of you parents as “Cs”, or wavy-type. The same could also be true of your parents parents, but beyond that it gets really unlikely that “none of your ancestors” had curly-type hair. Of course, it’s also possible that your curly hair might actually be wavy, or wavy-type. Outside the world of genes, wavy and curly are really just in the eye of the beholder.
