If a male donates a Y chromosome and the female donates an X chromosome what is the sex of the child?
We are learning new theories of gender/sexual preference every day as a result of more advanced studies. Until recently, however, it was generally accepted that a sperm with a y chromosome would produce a male child and a sperm with an x chromosome would produce a female child.
Biologists have discovered that things may no longer be quite that simple in some cases.
For example, traditional wisdom says that boys have an X and Y chromosome pair and that girls have an X and X pair.
They have learned that in cases of gender identity, some men are born with an extra X, sometimes even two extra Xs. In such a scenario, their gender chromosomal makeup can be XXXY, weakening the Y (male) sequence enough to cause gender confusion. The same is true of girls. Sometimes, they are born with only one X in the chromosomal pair which can result in more masculine traits.
But until these studies are more broadly accepted, it is fairly safe to say, that the Y half of a chromosome pair will result in a male offspring.
What else can I help you with?
Which chromosome carries the genes that determine the sex of a child as either male or female?
The chromosome that carries the genes determining the sex of a child as male or female is the X and Y chromosomes. Males have one X and one Y chromosome, while females have two X chromosomes.
Why do males play a role in determining the gender of a child?
Males play a role in determining the gender of a child because they carry the Y chromosome, which determines whether the child will be male or female. During fertilization, the sperm from the male can carry either an X or a Y chromosome, which combines with the X chromosome from the female to determine the gender of the child.
Is the sex offspring is determined by the chromosome the female parent gives?
Yes, the sex of the offspring is determined by the chromosomes contributed by the parents. The female parent always gives an X chromosome, while the male parent can contribute either an X or a Y chromosome, determining whether the offspring will be male (XY) or female (XX).
Does the father determine the gender of the child"?
No, the father's sperm carries either an X or Y chromosome, but it is the mother's egg that ultimately determines the gender of the child. If the egg is fertilized by a sperm with an X chromosome, the child will be female, and if it is fertilized by a sperm with a Y chromosome, the child will be male.
Why is it believed that the father determines the sex of his children?
In humans, the sex of an individual is determined by what combination of sex chromsomes he or she possesses. The sex chromsomes are called 'X' and 'Y' (because of their shape). Females possess two copies of the X chromosome, while males have one X and one Y. In more technical language, in humans the female is the homogametic sex and the male is the heterogameticsex. These terms give a clue to the answer to your question. Females can only produce one type of egg, those with an X chromosome, since they only have one type of sex chromosome (the X) to work with. Males, on the other hand, can produce two kinds of sperm: those carrying an X chromosome, and those carrying a Y. Since every human--male or female--carries at least one X chromosome, and the female can only produce gametes with X chromosomes, the male determines the sex of the child, because if he contributes another X chromosome, the child will be female, and if he contributres a Y, the child will be male. Note: in some other organisms, such as birds, the situation is reversed: the female is the heterogametic sex, and the male the homogametic sex. So in birds, the female determines the sex of the offspring.
How human male only responsible for the sex of a newborn child and female has no role in it?
It is true that the sex of the child is completely dependent on the male. This is because genetically men are XY and women are XX. This means that the woman can only donate the X chromosome to her child, while the father can either donate an X or a Y. If the father donates the X to the child, it will be XX and become a female, if the father donates a Y to the child, it will be XY and will become a male.
What kind of chromosomes do females transmit to offspring?
Female transmit 23 chromosomes to the offspring. She has that unique chromosome called as X chromosome. This is transmitted to the offspring. From male you get either X or Y chromosome. From XX chromosome you get female child. From XY chromosome you get male child.
What is geneotype in a normal male and female?
These genotypes are determined by a human's 23rd pair of chromosomes. If the subject is female, she has two X's reading XX. If it is male, then his genotype will read XY. There is a 50-50 shot of each. This is because a woman donates one chromosome (she only has two X's so it is inevitable that she will donate an X), and a man donates one of his. If a man donates his 'X' then there will be two X's and the child will be female. If he donates his 'Y' then the child will be male. Male is XY, female is XX. There are, however, other genotypes (XXY, XXX, XO...) and not all people have a phenotype that goes with their genotype.
What kind of chromosome do females transmit of offspring?
Female transmit 23 chromosomes to the offspring. She has that unique chromosome called as X chromosome. This is transmitted to the offspring. From male you get either X or Y chromosome. From XX chromosome you get female child. From XY chromosome you get male child.
What is the genotype of a male and female?
These genotypes are determined by a human's 23rd pair of chromosomes. If the subject is female, she has two X's reading XX. If it is male, then his genotype will read XY. There is a 50-50 shot of each. This is because a woman donates one chromosome (she only has two X's so it is inevitable that she will donate an X), and a man donates one of his. If a man donates his 'X' then there will be two X's and the child will be female. If he donates his 'Y' then the child will be male.Male is XY, female is XX. There are, however, other genotypes (XXY, XXX, XO...) and not all people have a phenotype that goes with their genotype.
Is it true that a mans sperm cells determine if a child will be a male or a female?
Yes, it is true that a man's sperm cells determine the sex of a child. Sperm carries either an X or a Y chromosome; if the sperm fertilizes an egg with an X chromosome, the child will be female (XX), and if it fertilizes an egg with a Y chromosome, the child will be male (XY). Therefore, it is the combination of the sperm's chromosome and the egg's chromosome that ultimately determines the child's sex.
Which parents gamete normally determines the sex of the child?
The father's gamete determines the sex of the child. Specifically, the presence or absence of a Y chromosome in the father's sperm will determine if the child will be male (Y chromosome present) or female (no Y chromosome).
Which chromosome carries the genes that determine the sex of a child as either male or female?
The chromosome that carries the genes determining the sex of a child as male or female is the X and Y chromosomes. Males have one X and one Y chromosome, while females have two X chromosomes.
Why do males play a role in determining the gender of a child?

During fertilization, the sperm from the male can carry either an X or a Y chromosome, which combines with the X chromosome from the female to determine the gender of the child.
Who are responsible for giving birth to a female child?
its actually the male who recognises the sex of a child bc the male has either has an x chromosome or a y while the female always has an x chromosome. so if an x from the male fertilizes the egg in the female, a female child would be born and if a y from a male fertilizes the egg then a male child would be born. All this scientific truth is contrary to what is believed in many primitive and ignorant societies and cultures of the world where they think that its the woman who is responsible for the birth of a female child.
The sex of a child is determined by?
In humans the sex of the offspring is determined by which sperm is able to fertilize the ovum. If a sperm containing the X chromosome fertilizes the ovum, a female offspring results. If a sperm containing the Y chromosome fertilizes the ovum, a male offspring results
Do you have a explanation about being a baby boy or girl?
Female humans have two X chromosomes, males have one X and on Y. The female contributes one X to the child. The male contributes either an X or a Y. This determines the sex of the child. If the sperm carries a Y chromosome, the child will be male, if the sperm carries an X chromosome the child will be female.
