is it true.........?

Question

Is it true that kids can be born with their DNA as a girls DNA is matched and have the body as a boy. Just wondering b/c I have kind of heard about it before. But i am not completely sure if it is true. Also could they be a boy like have the DNA as a boy and the body and then the Chromosomes split and re-attach to make a girl DNA but the boy still has the body.

Example.. ok i am a girl and when i was born they take ur DNA..i think..but anyways i had a girl dna...im not sure what the chromosomes are. but lets say A and B r together. Then later B and C connect making me a boy. Could that happen. Maybe that helped..

Answer 1

male vs. female sex organs are determined during early embryo development. the other physical differences between them are largely the result of the hormones that are produced from the sex organs. the default pathway is for the embryo to develop as a female. during development in males, a gene on the Y chromosome is expressed and the sex organs develop into those of a male. i know of a condition called androgen insensitivity syndrome where a person with an XY karyotype (male) does not respond to the male gene, and is physically and mentally a female. however, they are sterile. there are various conditions where a male's organs do not fully develop and they are treated as females even though they are technically male. and there are conditions where females develop more male attributes but are still pretty much female. (when you deliver a baby in a hospital, you either see a penis or you don't.) however, the chromosomal damage and repair suggested would never happen because it would have to happen in all the cells of the developing embryo.

Answer 2

Your Question has to Do With Phenotype Versus Genotype, Perhaps your Thinking of Androgen Resistance, Phenotypically Female, but Genotypically Male. Notably (Not that it has a Lot to Do With your Question), One Would Expect a Child to Be Phenotypically Female, but Barr Body Absent, See Barr Body and Lyonization.

Answer 3

question is kinda confusing but a genetically male person can develop breasts and even the sex organ can look like that of a female because of testosterone under secretion a female genetically can also look like a male because of hormonal imbalance

Answer 4

Not sure what you were getting at, but maybe this will help.
