Male & Female Chromosome Types

A developmentally correct human has 23 pairs of chromosomes. This is true for both human males and human females. Of the 23 sets, 22 sets deal specifically with conditions of heredity and somatic functioning. The last set is unique because it is the sex-determining chromosome. The letters X and Y are used to differentiate the male and female sex chromosome; X denotes the femaleness and Y denotes the maleness in the chromosome sets.

  1. XX (Female) Chromosome

    • The XX set of chromosomal arrangement is found specifically in the developmentally correct human female. In humans, the XX set will always be found in women. It is important to understand that non-human organisms such as plant and animal life also have chromosomes. Comparatively, non-human life has a broad breadth of total chromosomal sets; therefore, the total human set number will not always correspond with the total number of plant or animal sets in any other developmentally correct organism.

    XY (Male) Chromosome

    • The XY set of chromosomal arrangement is found specifically in the developmentally correct human male. When the XX female chromosome set and the XY male chromosome set are compared under high resolution microscopic examination, the XY male set appears different from the XX female set because the male-specific Y-chromosome differs in appearance from the XX female set and the X in the XY male set.

    XY / YY Chromosomal Arrangement

    • A single Y-chromosome must be present for the sex of the human to be considered male. The Y-chromosome is the expression of genetic maleness. All humans have an X-chromosome. In consideration to this fact, it is then understood that male humans are identified by an XY chromosome set. Conversely, YY arrangements do not appear in living humans because the total lack of an X-chromosome is incompatable with life.

    The Dominate Female X-chromosome Misinterpretation

    • Genetically speaking, sometimes the female X-chromosome is mistaken to be the dominant chromosomal expression. Developmentally, all species inherently develop with an XX female chromosomal set because there is no corresponding match in the XX female set that can be compared to the Y-chromosome in the XY male set. More X-chromosomes do not equate to sex-differentiating dominance. In the course of gestational maturation, almost all developmentally correct human beings first develop as an XX female.

    The X Chromosome and Genetic Abnormalities

    • It has already been established that all developmentally correct human beings have at least one X chromosome. When the parental partner passes his Y-chromosome to his offspring, the Y-chromosome is considered to be the dominant chromosome. It is when the male parent passes his Y-chromosome to the offspring that maleness is expressed on a genetic level; therefore, it is then understood that many more genetic abnormalities exist on the X-chromosome than do on the Y-chromosome.
