Hi, if there's a trisomy on the chromosome X (so its XXX) and if this woman could be capable of having children, what are >all< the possible genotypes, having in consideration the egg (being XXX) will be fertilized by a normal male (XY)?

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
