i was just wondering..

look.. if a child is born to a set of parents who are wizards but their child cant do magic.the child is said to be a squib... right...

but what if only one parent is a wizard..and the other parent is a muggle(pure muggle not a muggleborn)

what will they child be.. will he/she still be a squib?...or will the child be a muggle?

Confused Confused Confused Confused Confused Confused

I believe it would be a squib because squibs are decedents of wizards and witches and muggles are decedents of two none-Magical folk.

A Squib is almost the opposite of a Muggle-born wizard: he or she is a non-magical person born to at least one magical parent. Squibs are rare; magic is a dominant and resilient gene.

How is magic a dominant gene? That contradicts what she said before. She said that a Muggle-born witch or wizard have magical relatives on both sides in their ancestry, and they inherit that gene from generation to generation, but the phenotype of magical ability has an overwhelming chance not to show up. This can only mean that magic is a RECESSIVE ALLELE, and the phenotype can only surface id someone inherits both recessives. It seems like JK has a bit (a lot) to learn about basic genetics.

Squib, I think! And, as it has already been said, wouldn't magic powers be the dominant?

Dominant genes can lay dormant. Confused But it's rare, and so are squibs. So it fits perfectly, actually.

Yeah. Both of my parents are brunettes, and my sister is a ginger. I think the red hair came from my grandmother, and there aren't very many redheads in the family.

My uncle has blonde hair, and neither of my grandparents, nor their parents, had blonde hair. My dad and his other brother used to make jokes about their mom and the milkman. But of course they were only jokes... somewhere along the trait line there was a blonde gene just squatting there... not unlike Hermione's wizarding gene. Genetics isn't perfect, that's what makes us unique.

but what abt what habs4life said? how did these muggleborns acquire magic, if magic is based on the genes?

Magic is a dominant gene... dominant genes can be dormant, too. Two blonde haired people can have a baby with brown hair.

No, they can't. Blond hair is a result of a homozygous recessive genotype. Two blond-haired people may therefore only pass this combination to their children. Ginger kids are possible, as well, but this is a result of mutation. So it also doesn't really make sense that ALL the Weasleys have red hair and freckles, either, even if both Arthur and Molly were ginger. What are the chances that all of the zygotes would undergo the exact same mutation? Getting back on topic, people with homozygous genotypes for hair may only pass their own color of hair to their offsrping, barring mutation. It is possible for two brown-haired people to have a blond kid, IF and only if both parents are heterozygous. Only in this case is it possible to inherit two recessive alleles that will reveal the phenotype of blond hair. But it certainly can't work for two blonds to have a brown-haired kid. If you can provide me with an example of a natural blond couple that produced brown-haired offsrping, I will admit I am wrong about this, but I don't believe I am.

In addition, I assume that the magic gene is carried on the X chromosome, because if it were on the Y then females would not inherit it. But that should mean that a boy with a wizard father and a Muggle mother would be a Muggle without a doubt, since the X chromosome he inherits is from the Muggle side, and as such does not carry the gene.

Here is a link that can clear stuff up http://72.14.205.104/search?q=cache:6NrZ5uOqUPkJ:www.squashedfrogs.co.uk/resources/2005/10/harry_potter_genetics.ppt+harry+potter+genetics&hl=en&ct=clnk&cd=1&gl=ca

If the magical gene was recessive, then there would be more squibs than wizards. Period. Therefore, the magical gene must be dominant. Gene mutations are possible, as you said. Also, dominant genes can lay dormant. Neither is common, therefore it is rare, as Ron clearly said it is.
It's a magical gene, lol. Hun, stop taking this so seriously. It's a book about magic, not science or science fiction. If you were hoping JK Rowling is a scientist, then maybe someone should have told you she was an author so you wouldn't have been disappointed by the book.

But if the magical allele is dominant, then it should be impossible for a Muggle-born wizard to be produced, at least according to Mendelian genetics. Unless Rowling follows her own patterns of genetic heredity? Bottom line, the moment she used the word "gene" in those interviews, she was setting herself up for heavy criticism.

Genetics are not perfect. There are mutations and dormant genes. If genetics was a perfect tblueprint for human bodies, then every single person would never have Down Syndrome, have red hair, or even different shades of eye color.

Yepp. Thats true, so therefore, the child would be a squib.

Yep, I agree that it would be a Squib. Because if one of its parents is a wizard/witch that makes that person a Squib. Thanks.
