Y chromosome polymorphisms in medicine. This is because the X chromosome is large and contains many more genes than the smaller Y chromosome. They can be caused by missing or extra copies of the sex chromosomes or by structural changes in these chromosomes.

The "a" r ecessive allele will be expressed in his phenotype. Both alleles influence the genetic trait or determine the characteristics of the genetic condition. To read about how chromosomal conditions occur, please see Are chromosomal disorders inherited? Y-chromosome deletions are a frequent genetic cause of male infertility.

  • 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.
  • Sex Linked Genes. A particularly important category of genetic linkage has to do with the X and Y sex chromosomes.
  • If a gene is found only on the X chromosome and not the Y chromosome, it is said to be a sex-linked trait. As the gene that expresses the trait is located on the sex chromosome, sex linkage is linked to the gender of the offspring.
  • Chromosomes are long segments of genes that carry hereditary information.
  • A sex chromosome , also referred to as an allosome , heterotypical chromosome , or heterochromosome , [1] [2] or idiochromosome [3] is a chromosome that differs from an ordinary autosome in form, size, and behavior.

These genes are either Y-linked if found on the Y chromosome or X-linked if found on the X chromosome. Deletions of small amounts of genetic material in certain areas of the Y chromosome lead to a condition called Y chromosome infertility. Retrieved In Drosophila, the gene for eye color is located on the X chromosome.
