The gender phenotype changes from being a boy to being a girl. This condition is called Swyer syndrome. You can read more about the specifics on Wikipedia.

What is the sry gene?
The SRY gene is a gene on the Y chromosome required for the development of testes. It stands for Sex determining Region on Y chromosome.
Is it possible for an XY embryo to develop as a female if the SRY gene on the Y chromosome is not present?
In humans, yes.By default, humans are female. A functional SRY gene stimulates the body to produce male characteristics that override the underlying female pattern. If the SRY gene is absent (or, as sometimes happens, mutated) an individual who is chromosomally XY will develop as a female. This is one cause of Swyer syndrome.
What happens to the expression of the lacl gene if lactose is not available in the cell?
there is no change--the lacl gene is constitutively expressed
An expressed gene is one that what?
a gene being expressed means it is shown, for example if you have the gene for brown eyes and the gene for blue eyes, only one can be expressed. if you have brown eyes that gene is expressed, if not the blue-eye gene is expressed.
A male with a missing SRY gene would be phenotypically?
female
Is the SRY gene responsible for testosterone?
Indirectly. The SRY gene is responsible for activating the gene responsible for testosterone production (thereby causing 'maleness' in a developing foetus).

What happens to a gene for a protein that is not used much in the cell?
Nothing "happens" to it. When a gene is not actively being copied or expressed it is folded up and stored till it is needed again.
Why testes descends down in human male fetus before birth?
Look up the SRY gene located on the sex chromosomes. The SRY gene when turned on in epistatis controls that.
An expressed gene is one that what?
a gene being expressed means it is shown, for example if you have the gene for brown eyes and the gene for blue eyes, only one can be expressed. if you have brown eyes that gene is expressed, if not the blue-eye gene is expressed.
Is an expressed gene turned off?
No. If a gene is expressed, it is turned on.
Expression of the SRY gene causes an embryo to develop what?
Into a Male
A male with a missing SRY gene would be phenotypically?
female
Which parts of a gene are expressed as protein?
Coding sequences of a gene are expressed as protein
What does it mean for a gene to be off?
How is a gene not expressed
