May 12, · A sex chromosome is a type of chromosome responsible for the chromosomal determination of the sex of an individual, e.g. whether a female or a male. Sex determination is based on the genes responsible for the development of the corresponding sexual characteristics of the organism/5.
The XY sex-determination system is the sex-determination system found in humans, most other mammals, some insects, some snakes, and some plants. In this system, the sex of an individual is determined by a pair of sex chromosomes. Females typically have two of the same kind of sex chromosome (XX), and are called the homogametic sex. a chromosome that determines the sex of individuals; it carries genes that transmit sex-linked traits and conditions.

Chromosomes in humans can be divided into two types: autosomes (body chromosome(s)) and allosome (sex chromosome(s)). Certain genetic traits are linked to a person's sex and are passed on through the sex chromosomes. The autosomes contain the rest of the genetic hereditary information. All act in the same way during cell division. Nov 16, · Sex Chromosomes Definition. Sex chromosomes are chromosomes that determine whether the individual is male or female. Though these two chromosomes pair with each other during meiosis, there is usually very minimal homology or recombination between them, primarily because of a large difference in their genetic content and size/5(67).
