What else can I help you with?
A male with a missing SRY gene would be phenotypically?
A male with a missing SRY gene would typically have a female phenotype because the SRY gene on the Y chromosome is responsible for initiating male development. Without the SRY gene, the individual would develop along the female pathway.
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 sry gene?
The SRY gene, also known as the sex-determining region Y gene, plays a critical role in the development of male characteristics in mammals. It is located on the Y chromosome and is responsible for initiating the development of the male reproductive system during embryogenesis. Mutations or abnormalities in the SRY gene can lead to disorders of sex development.
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.
Which specific gene, if any, is located on a sex chromosome?
The specific gene located on the sex chromosomes is the SRY gene, which is responsible for determining male sex characteristics.
What gene causes a fetus to become male?
The SRY (Sex-determining Region Y) gene, located on the Y chromosome, is responsible for triggering male sex determination in a fetus. When the SRY gene is expressed, it initiates the development of testes, which subsequently produce male hormones such as testosterone. This hormonal environment leads to the development of male physical characteristics and reproductive structures. In the absence of the SRY gene, the default pathway leads to female development.
A male with a missing SRY gene would be phenotypically?
A male with a missing SRY gene would typically have a female phenotype because the SRY gene on the Y chromosome is responsible for initiating male development. Without the SRY gene, the individual would develop along the female pathway.
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).
Is it possible for an XY embryo to develop as a female if the SRY gene on the Y chromosome is not present?

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.
Expression of the SRY gene causes an embryo to develop what?
Into a Male
What is SRY gene and what does it determine?
The SRY gene, or Sex-determining Region Y gene, is located on the Y chromosome and plays a crucial role in male sex determination. It encodes a transcription factor that initiates the development of male gonads, leading to the formation of testes and the production of male hormones such as testosterone. The presence of the SRY gene typically results in the development of male physical characteristics, while its absence usually leads to female development. Thus, the SRY gene is essential for initiating male sexual differentiation during embryonic development.
Is an expressed gene turned off?
No. If a gene is expressed, it is turned on.
What is the effect of the SRY gene?
The SRY gene, located on the Y chromosome, plays a crucial role in male sex determination. It encodes a protein that triggers the formation of testes, leading to the production of male hormones (androgens) that promote the development of male reproductive structures. In the absence of the SRY gene, the default developmental pathway is female, resulting in the formation of ovaries and female reproductive anatomy. Thus, the SRY gene is essential for the differentiation of male characteristics during embryonic development.
Which parts of a gene are expressed as protein?
Coding sequences of a gene are expressed as protein
