Race is a man-made construct, and has no genetic or biologic component.
If you are a male, you got a Y chromosome from your father and an X chromosome from your mother.
If you are a female you got an X chromosome from your father and a second X chromosome from your mother.

In human which sex chromosome determines if an offspring is a male or female?
In humans, which sex chromosome determines if an offspring is a male or female?
Which male genotype in the ZW sex chromosome system?
In the ZW sex chromosome system, the male genotype is ZZ. The letter Z represents the presence of a dominant male-determining gene, while the letter W represents the absence of this gene, which determines female development. Therefore, individuals with the ZZ genotype develop as males in this system.
What number of chromosomes determines if you are a male or female?
the amount of x and y chromosomes you have.
How does the gene for hyperkalemic periodic paralysis present?
The gene for hyperkalemic PP affects virtually all who inherit it, with no difference in male-vs.-female expression.
How much chromosomes do each male and female contribute toward the formation of a new human?
The male and female each contribute 23 chromosomes, one of which determines the sex of the baby/new human
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 determines if you are male or female?
TDF (testicular determining factor) is a gene found on the Y chromosome that will determine if one is male or female. If it is present, one is a male. If it is absent, one is a female.
Is Gene a male or a female name?
Gene is a male name
Which sex chromosome determines if an offspring is male or female in humans?
In humans, which sex chromosome determines if an offspring is a male or female?
What gene determines whether a human will develop into a male or female?
The Y-chromosome. Think of it this way: Each person contains the genes to be a female. These genes are inherited on the X-chromosome which every normal person has. However, if you have a Y-chromosome, you now posses the genes to make a male, and are thus will be a male.
In human which sex chromosome determines if an offspring is a male or female?
In humans, which sex chromosome determines if an offspring is a male or female?
A male with a missing SRY gene would be phenotypically?
female
Which male genotype in the ZW sex chromosome system?
In the ZW sex chromosome system, the male genotype is ZZ. The letter Z represents the presence of a dominant male-determining gene, while the letter W represents the absence of this gene, which determines female development. Therefore, individuals with the ZZ genotype develop as males in this system.
When does female gene dominate the male gene?
There is not really anything called a male or female gene. There are sex chromosomes: X and Y. If a baby has XY (one from each parent), that child will be male. If the baby has XX, a girl is the result. The Y chromosome doesn't actually dominate but it has all the genes that produce male characterics. If a child is born without it, it will be female.
What determines weather a baby box turtle will be male or female?
Incubation temperature.
What makes a female a female and what makes a male a male?
Their DNA. Sex is decided by chromosomes from the male at fertilization. if you are wondering what "officially" makes a female a female, it's DNA and ability to reproduce per authorities.
Are male or female calicos rare?
Males are rare, if they exist at all. The gene for the calico fur is carried by the female chromosome.
