Yes, an embryo can develop with one X chromosome, rather than the XX or XY chromosome pair. An example of this is girls born with Turner's syndrome, who have only one X chromosome.

What determines whether an embryo will become male or female?

The sex of an embryo is determined by the presence or absence of a Y chromosome. If the embryo has a Y chromosome, it will develop as male. If no Y chromosome is present, the embryo will develop as female.


What chromosome tells us the sex of a human?

The X and Y sex chromosomes. If the embryo inherits an X and Y chromosome, it will be male. If the embryo inherits two X chromosomes, it will be female.


How is the sex of an embryo determined?

The sex of an embryo is determined by the combination of sex chromosomes inherited from the mother and father. Typically, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). The presence of a Y chromosome triggers the development of male characteristics.


What determines whether the indifferent gonads in a mammalian embryo will develop into ovaries or testes?

It probably has to do with the predetermination of the baby's sex. If the father contributed a Y chromosome, then the indifferent gonads would develop into testes. If an X was contributed then they would develop into ovaries.


How many sex chromosomes does a male embryo have?

An embryo, male or female, usually has two sex chromosomes, one from mom, one from dad. In a male's case, they would be XY. Rarely, nondisjunction occurs, and a child winds up XXX, XXY, XYY, or X. XXX and X become female, and XXY and XYY become male. So, it is theoretically possible for a male embryo to have three sex chromosomes.


Why does a single sperm have only one sex chromosome?

A sperm cell contains either an X or Y sex chromosome, determining the biological sex of the offspring when combined with an egg. This ensures that the resulting embryo will have the proper number of sex chromosomes (XX for female or XY for male) to develop into a healthy individual.


In humans a male has?

One X chromosome and one Y chromosome, which determines male sex characteristics.


Which sex chromosome do sperm cells carry?

Sperm cells are of two types. One type carries a Y chromosome, while the other type carries an X chromosome. This is the reason why the Spermatid is the 'deciding factor' in whether a baby will be male or female. The Ovum always carries an X chromosome.


Why does Lesch-Nyhan syndrome affect males?

Lesch-Nyhan syndrome is an X-linked recessive disorder, meaning the gene mutation responsible for the condition is located on the X chromosome. Males have one X chromosome and one Y chromosome, so if they inherit the mutated gene on their X chromosome, they will develop the disorder. Females have two X chromosomes, so they are less likely to inherit the mutation on both X chromosomes.


What determines the sex of a human?

Whether they have 2 X chromosomes= girl, of one X chromosome and one Y chromosome= boy


Why are most sex-linked traits found in the X chromosome?

Most sex-linked traits are found on the X chromosome because males have only one X chromosome, so any gene on the X chromosome will be expressed in males. In females, who have two X chromosomes, one X chromosome can compensate for any harmful gene on the other X chromosome.


What X and Y chromosomes combine in making?

In humans, typically a combination of one X chromosome from the mother and one X or one Y chromosome from the father determines the biological sex of the offspring. A fetus with XX chromosomes typically develops as female, while those with XY chromosomes develop as male.
