What complications could occur if male and female sex chromosomes were XY?

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

Could crossing over occur during second meiotic division?
No, tips of homologous chromosomes cross over in Meiosis I. There are no homologous chromosomes by Meiosis I.
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.
Does chiasmata occur in mitosis?
no, it happens in meiosis, it is when the bivalent chromosomes cuts and rejoins so that there is variability in the chromosomes.
Somatic mutations occur in sex chromosomes and can be inherited?
true
When does duplication of chromosomes occur?
when does the duplication of chromosomes occur?
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.
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.

Chromosomes normally occur as homologous pairs in?
Chromosomes normally occur as homologous pairs in a diploid cell. These refers to matching pairs of chromosomes which are found in the cell.
What complications can occur as a result of a CEA test?
There are no complications or side effects of this test.
Duplication of chromosomes occur in?
The replication of the chromosomes occurs during interphase.
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.
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.
