This can occur in a very rare condition where genetically the baby is a boy (XY), but during that time of sexual determination (7th week of the pregnancy), the testosterone gene is not turned "on" making the XY baby not a boy but a fully functional girl.
If this fully functional XY girl meets up with a XY boy and they decide to have children, this is what might happen:
XY x XY
- XX = girl baby - 25% probability
- XY = boy baby - 50% probability
- YY = lethal gene -- miscarriage - 25% probability

What does it mean when a human has two X chromosomes?
When a human has two X chromosomes, it typically indicates that they are female, as females usually have two X chromosomes (XX) while males have one X and one Y chromosome (XY). This chromosomal configuration is associated with the development of female secondary sexual characteristics and reproductive systems. However, variations can occur, such as in individuals with Turner syndrome (a single X chromosome) or Androgen Insensitivity Syndrome, where individuals may have XY chromosomes but develop female characteristics.
Why do karyotypes always show chromosomes at the point when cell division is about to occur?
They show chromosomes at the point when cell division is about to occur because the chromosomes are condensed and aligned which makes it easy to tell if there are the correct number and configurations of the chromosomes.
When do homologus chromosomes occur short answer please thankss?
Homologous chromosomes occur during meiosis. Meiosis reduces the chromosome number by half.
What is the functional role of forming tetrads in meiosis and or mitosis?
Tetrads only appear in meiosis. The tetrad is the joining of four chromosomes in prophase I of meiosis. Two male duplicated chromosomes and two female chromosomes. The most important role of tetrad formation is ' crossing over. ' This is the exchange of genetic information between the male and female chromosomes. The material, whole genes, is physically swapped between the male and female chromosomes.
Somatic mutations occur in sex chromosomes and can be inherited?
true
Do you all start out being female?
This is the theory because all femle ova have female chromosomes.. Sperm have male and female chromosomes. If the sperm containing female chromosomes then nothing changes during fertilization. If male chromosomes, then changes take place to cause the cells to produce a male. There is scientific theory that this may be a cause of homosexuality in that the changes do not occur as expected. But this is only theory. --- They don't necessariy start as female, but they do have female organs. It is the presence of chemicals (due to Y chromosome) that forms the male organs from the female organs later on.
When does duplication of chromosomes occur?
when does the duplication of chromosomes occur?
What are some complications of rhinoplasty?
There are many complications that could occur, such as necrosis, meaning death of tissue that would need to be removed. Infection could occur which could move to the bloodstream. Commonly mild side effects are all that one would experience such as swelling, bruising, and mild bleeding.
Why are male mutation rates higher than female?
This is because mutations occur in x chromosomes. The male, who has "xy" sex chromosomes, will have the mutation if it is present in the x chromosome. Females, there is a smaller chance because there are two "xx" chromosomes, which reduces the chance that the mutation will be present.
Duplication of chromosomes occur in?
The replication of the chromosomes occurs during interphase.
What complications may occur after fundoplication?
Complications, though rare, can occur during fundoplication. These complications can include injury to such surrounding tissues and organs, as the liver, esophagus, spleen, and stomach.

What complications can occur with leukocytosis?
nothing
What complications can occur as a result of a CEA test?
There are no complications or side effects of this test.
What kind of chromosomes do the body cells of humans have?
All Human Body Cells, also called somatic cells, have 46 chromosomes. These 46 occur is 23 pair. The first 22 pair are called autosomes. The 23rd pair are the sex chromosomes, xx for female, xy for male.
When pregnancy could occur?
If you are a sexually active female, pregnancy can occur. Birth control will help prevent pregnancy, but is not guaranteed.
Why do karyotypes always show chromosomes at the point when cell division is about to occur?
They show chromosomes at the point when cell division is about to occur because the chromosomes are condensed and aligned which makes it easy to tell if there are the correct number and configurations of the chromosomes.
