More than 95% of the Y chromosome is male-specific (4) and a single copy of the Y chromosome is able to induce testicular differentiation of the embryonic gonad. The Y chromosome acts as a dominant inducer of male phenotype and individuals having four X chromosomes and one Y chromosome (49XXXXY) are phenotypically male. (5) When a Y chromosome is present, early embryonic testes develop around the 10th week of pregnancy.
Mitochondrial DNA is not one of the 23 chromosomes you obtain from both of your parents. The X chromosome is different. The X chromosome is one of the 23 pairs of chromosomes. The 23rd pair is the pair that dictates the gender of the child. If a child has an X and a Y, itâs a male. Remember that the father contributes the Y chromosome to male children only. If the child has two X chromosomes, itâs a female.
