A sex chromosome is the chromosome that determines the sex of an organism. Autosomes are homologous chromosomes that means these chromosomes contain same genes in same order along with their chromosomal arms. Sex chromosomes differ from the autosomes in size, form, and behavior. Each cell of humans usually contains 23 pairs (46) chromosomes. 22 pairs of them are autosomes, while the 23rd pair is the sex chromosome.The primary oocyte stage in females is diploid that contains 44 autosomes and 2 sex chromosomes (XX), that means 46XX. The secondary oocyte stage contains 22 autosomes and 1 sex chromosome (X), that means 23X. Ovum contains 22 autosomes and 1 sex chromosome (X), that means 23X. The primary spermatocyte contains 44 autosomes and 2 sex chromosomes (46XY). Secondary spermatocyte contains 22 autosomes and 1 sex chromosome which is either X or Y (23X or 23Y). The spermatozoan also contains 22 autosomes and 1 sex chromosome (23X or 23Y).The complete table is as follows: Stage in Female # of autosomes and types of sex chromosomes Stage in Male # of autosomes and types of sex chromosomes Primary oocyte # 44 and # 2 (XX) Primary spermatocyte # 44 and # 2 (XY) Secondary oocyte # 22 and # 1 (X) Secondary spermatocyte # 22 and # 1(X or Y) Ovum # 22 and # 1 (X) Spermatozoan # 22 and # 1(X or Y)
