How do you tell the difference between male and female sex chromosomes?

We have to look at pics of chromosomes(karyotes) and determine what disorder they have but we have to give them a notation as well.(number of chromosomes total and sex) Thanks so much!!How do you tell the difference between male and female sex chromosomes?Aight, here's what I think you want to know: The X chromosome is bigger than the y chromosome.How do you tell the difference between male and female sex chromosomes?xx and xy chromosomes! xx are female and xy are male. the disorder i think they have is that some men are colorblind. As far as notation i'm not to sureHow do you tell the difference between male and female sex chromosomes?The male X chromosome showed a different replication behavior in comparison to that of the female X chromosome and autosomes. It is concluded that the male X chromosome finishes its replication earlier than the female X chromosome. Moreover, the time needed for a complete replication cycle of individual identical replication units was found to be shorter in the male than in the female X chromosome. Although the whole X chromosomes behave different there were no differences observed in the sequence of the discontinuous labeling patterns of the two types of X chromosome. One autosomal replication unit was observed which showed a different replication behavior in males and females. The possible origin of the differential behavior of the two X chromosomes is discussed in terms of their difference in degree of polyteny.
