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.
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.
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.
What determines the sex of an individual?
Presence or absence of the Y chromosome
The risk factor that also determines an individual's sex is?
gender
What is a the male and female genotype?
The genotype for a male is XY. A female is XX. The 23rd homologous pair is the sex gene that determines this.
What is the chromosome pair XX?
Generally, since the sex determining region is on the Y chromosome, this person is male. The SRY is a gene control area that determines male sex. Female is the default body plan in humans; males are made.
What determines the genes that determines the sex?
the answer is sex chromosomes
What determines whether a mammal will be male?
In mammals, the presence or absence of a Y chromosome controls the sex of the individual.
One of the pair of chromosomes that determines the sex of an individual?
The 23rd pair in a karyotype shows if it will be male or female
A trait which is inherited on sex chromosomes is?
Sex-linked traits have alleles that are passed from parent to child on a sex chromosome.
How does y chromosome determine maleness in humans?
XX = female. XY= male because the Y chromosome has SRY gene (Sex-deterimining Region Y). The SRY gene in mammals makes the body produce testis which makes testosterone making the foetus male. For more information, please see the related link below.
