What chromosome contains a gene that causes the gonads of an embryo to develop testes?

If you're a mammal, the key gene that initiates gonad development into testes (the Sry gene) is located on the Y chromosome. However, be aware that while gene necessary for the initiation of the male developmental program is located on the Y chromosome, many genes absolutely essential for complete testes and male development are distributed across many other chromosomes.

An embryo is always stimulated to develop into a female because it?
lacks a Y sex chromosome
Why does an embryo with 2 X chromosomes develop into a female?
since it "lacks" a Y chromosome, the production of testosterone is low and the baby develops female.
Where the embryo grows and develop?
An embryo grows and develops in a females womb.
Would the separation of an egg and it's polar body soon after fertilization harm the development of an embryo?
No. The polar body is essentially a trash can. Excess DNA is placed there, but since it contains little cytoplasm it cannot develop into an embryo.
What organ does the embryo develop in?
Uterus
Can an embryo develop with one x chromosome?
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.
An embryo is always stimulated to develop into a female because it?
lacks a Y sex chromosome
Expression of the SRY gene causes an embryo to develop what?
Into a Male
Why does an embryo with 2 X chromosomes develop into a female?
since it "lacks" a Y chromosome, the production of testosterone is low and the baby develops female.
What is the chromosome number for an embryo?
An animal will have a full set of chromosomes (2n) as an embryo.
What is an archegonium?
An archegonium is a multicellular reproductive structure which contains a large, non-motile gamete and within which an embryo will develop.
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.
What is y-chromosoze?
Y chromosome is the 2nd chromosome in a male homolouge it has the contribution in sex determination of the embryo.
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 does a bear embryo develop?
The same way that a human embryo or any other mammalian embryo does.
Where the embryo grows and develop?
An embryo grows and develops in a females womb.
Is it a false pregnancy if the embryo does not develop?
If there was an actual embryo, it was not a false pregnancy.
