Sex-chromosome Synonyms

Either of a pair of chromosomes, usually called X and Y, that in combination determine the sex of an individual in many animals and in some plants.

Sex chromosomes carry the genes that control the development of reproductive organs and secondary sex characteristics. In some organisms, sex is determined by environmental influences.
