How is the genetic sex of a child determined?
The genetic sex of a child is determined by the combination of sex chromosomes inherited from the parents. Typically, a child with two X chromosomes is female, while a child with one X and one Y chromosome is male.
What is a sex-linked trait and how does it differ from other types of genetic traits?
A sex-linked trait is a genetic characteristic that is determined by genes located on the sex chromosomes, specifically the X or Y chromosomes. This differs from other types of genetic traits because they are not influenced by the sex chromosomes and can be located on any of the other chromosomes in the cell.
What age can you tell if the embryo is a male or female?
Typically, the sex of an embryo can be determined through ultrasound around 18-20 weeks of pregnancy. Genetic testing through techniques like preimplantation genetic testing can also be done at earlier stages to determine the sex of the embryo.
Is human eye color a sex linked character?
No, human eye color is not a sex-linked trait. It is determined by multiple genes and is inherited in a complex manner involving both genetic and environmental factors.
What determines the sex of an organism and how is it determined?
The sex of an organism is determined by its genetic makeup, specifically the combination of sex chromosomes it inherits. In most species, including humans, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). The presence of a Y chromosome typically triggers the development of male characteristics.

What is the difference between 'sex-liked' and 'sex-determined'?
Sex-liked means liking sex and sex determined is the resolution to have sex.
In what condition is crocodile sex formed?
The sex of developing crocodilians is determined by the incubation temperature of the eggs. This means crocodilians do not have genetic sex determination, but instead have a form of environmental sex determination which is based upon the temperature embryos are subjected to early in their development. Crocodile embryos do not have sex chromosomes, and unlike humans sex is not determined genetically. Sex is determined by temperature, with males produced at around 31.6 °C, and females produced at slightly lower and higher temperatures. The average incubation period is around 80 days, and also is dependent upon temperature.
What age can you tell if the embryo is a male or female?

What two factor that determined a persons status within early Chinese families?
The status or each person in a Chinese extended family depended on his/her age and sex.
What can be determined by studying genetic similarities between two species?
Genetic courses of behavior can be determined by studying genetic similarities between two species.
Is human eye color a sex linked character?
No, human eye color is not a sex-linked trait. It is determined by multiple genes and is inherited in a complex manner involving both genetic and environmental factors.

Does one testicle produce males and the other females?
No, both testicles are responsible for producing sperm that contains genetic material to determine biological sex. The sex of an individual is determined by the chromosomes present in the sperm that fertilizes the egg.
What are similarities between sex linked gene and carrier?
Both sex-linked genes and carriers involve the inheritance of a specific gene. Sex-linked genes are located on sex chromosomes, while carriers typically refer to individuals who possess a recessive genetic mutation but do not exhibit the associated trait. In both cases, these genetic traits can be passed down to offspring.
The dimension of sex which refers to x and y chromosomes is called?
The dimension of sex which refers to X and Y chromosomes is called genetic sex.
