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 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.
What happens when SRY gene is not expressed?
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.
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.
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
Can a man be born with a vagina on his leg?
Generally, no, Males have to have somthing called the SRY gene that determines their gender, however there may be deficits in the pathway that this gene acts. thus producing a "vagina" but it may actually not be a normal vagina... secondly it is possible to have it on his leg, however this is very uncommon.
Describe where the human SRY gene resides and its significance?
It is the gene on the Y chromosome important for male development.
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 is the function of the gene SRY?
located on the Y chromosome and codes for a protein that regulates genes that control development of testes
Testis-determining factor is found in or on?
Testis-determining factor (TDF) is found on the Y chromosome of mammals. It is a gene called SRY (sex-determining region Y) that plays a crucial role in the development of testes and the determination of male sex characteristics.
Why is cancer always a genetic disease?
because it is an inactive gene that is passed down by the parent and it can be triggered... i think.... sry.. lol hope it helped
