However, there are other differentiating features between these chromosomes. Some differences include size, number of genes and even abnormal chromosome ...
Is XX male or female? XX is female. One X chromosome is inherited from the mother and one from the father. The X chromosome itself is about three times larger than the Y chromosome.
sex chromosome, either of a pair of chromosomes that determine whether an individual is male or female. The sex chromosomes of human beings and other mammals are designated by scientists as X and Y. In humans the sex chromosomes consist of one pair of the total of 23 pairs of chromosomes.
In the XY sex-determination system, the female-provided ovum contributes an X chromosome and the male-provided sperm contributes either an X chromosome or a Y chromosome, resulting in female (XX) or male (XY) offspring, respectively.
The X chromosome has some instructions to make body parts that all people have, and others for body parts that only females have. A karyotype is a complete set of chromosomes from an organism or species.
In most mammals, females are XX, and can pass along either of their Xs; since males are XY they can pass along either an X or a Y. Females in such species receive an X chromosome from each parent while males receive an X chromosome from their mother and a Y chromosome from their father.
In humans and most other complex organisms, one copy of each chromosome is inherited from the female parent and the other from the male parent. This explains why children inherit some of their traits from their mother and others from their father.
