Chromosomes play a crucial role in determining a child's gender, as they are inherited from the parents. Humans have 23 pairs of chromosomes, with one pair being the sex chromosomes: XX for females and XY for males. The mother contributes an X chromosome, while the father can contribute either an X or a Y chromosome. Thus, the combination of these chromosomes ultimately determines the child's gender.
autosomal trait
One characteristic arising from genes located on gender determining chromosomes is the development of primary and secondary sexual characteristics, such as genitals and reproductive organs. Additionally, these genes can influence hormone levels and patterns of gene expression that contribute to differences in physical and physiological traits between males and females.
The presence or absence of specific sex chromosomes (XY for male, XX for female) is the most important factor in determining the gender of a hair sample. Other factors, such as hormone levels, can also provide clues to the sex of the individual from whom the hair sample came.
Genetic chromosomes
A karyotype is a representation of an individual's set of chromosomes, showing the number, size, and shape of chromosomes. It does not determine gender; rather, it provides information on potential genetic conditions or disorders. Gender is typically determined by the presence of XX chromosomes in females and XY chromosomes in males.
One example of a characteristic arising from genes located on chromosomes that are not gender determining is eye color. Eye color is determined by multiple genes located on different chromosomes and is not specifically tied to the X or Y chromosomes that determine gender.

The role of chicken sex chromosomes in determining the gender of chickens is similar to that in humans. Female chickens have two Z chromosomes (ZW) and male chickens have one Z and one W chromosome. The presence of the W chromosome determines the chicken's gender as female, while its absence results in a male chicken.
Fish sex chromosomes play a crucial role in determining the gender of fish by carrying genetic information that determines whether an individual develops as a male or female. The presence or absence of specific sex chromosomes, such as the Y chromosome in males, influences the development of reproductive organs and secondary sexual characteristics in fish.
No, an embryo's gender cannot be changed after it is conceived. The gender of a person is determined at the moment of conception based on the combination of sex chromosomes inherited from the parents.
The paired chromosomes that determine an individual's gender are called sex chromosomes.
In humans, gender is typically determined by the combination of sex chromosomes received from the parents. Males typically have one X and one Y chromosome (XY), while females have two X chromosomes (XX).
