The only homologous chromosome pair in humans that is not identical is the sex chromosomes, specifically the X and Y chromosomes.
Males have 44 homologous chromosomes, or 22 pairs. Females are 46 and 23 respectively since they have homologous sex chromosomes.
Homologous chromosomes are chromosome pairs, one from each parent, that are similar in length,gene position, and centromere location. The position of the genes on each homologous chromosome is the same, however the genes may contain different alleles.A human karyotype shows the complete set of human chromosomes. Human cells contain 23 pairs of chromosomes for a total of 46. Each chromosome pair represents a set of homologous chromosomes. In males, the sex chromosomes X and Y are homologues. In females, both X chromosomes are homologues.
The exceptions to the rule that every chromosome is part of a homologous pair are the gametes. Gametes are eggs and sperm, and each cell has only 23 chromosomes, which form pairs in the zygote after fertilization.
The pair of sex chromosomes (X and Y) is not homologous in a normal male karyotype. Males have one X and one Y chromosome, while females have two X chromosomes.

It is found on the non homologous part of the X chromosome.

The human male has both an X and Y chromosome which determines the sex of an offspring. Female only have the X chromosome.
The 23rd pair of chromosomes are the sex chromosomes. In female humans, both sex chromosomes are homologous, and characterized as XX. In male humans, one sex chromosome is an X chromosome and the other is a much smaller, nonhomologous Y chromosome, and is characterized as XY.
Humans have 22 pairs of homologous non-sex chromosomes (called autosomes), and one pair of sex chromosomes, making a total of 46 chromosomes in a genetically normal human.Each member of a pair is inherited from one of the two parents. In addition to the 22 pairs of homologous autosomes, female humans have a homologous pair of sex chromosomes (two Xs),while males have an X and a Y chromosome.
The male human is represented by a sex chromosome consisting of one X chromosome and one Y chromosome (XY).
The pair of sex chromosomes (X and Y) is not homologous in a normal male karyotype. Males have one X and one Y chromosome, while females have two X chromosomes.
A pair of chromosomes is called a "chromosome pair."Generally, the two chromosomes in a pair are "homologous chromosomes."An individual form of a gene is called an "allele." (For example: if someone has genotype "Aa", they have two different alleles, "A" and "a")
The two sets of chromosomes that come from the female parent are the two X chromosomes, while the two sets from the male parent are one X and one Y chromosome. This combination determines the genetic sex of the offspring, with XX resulting in a female and XY resulting in a male.
