Which parent carries the gene to determine if you will have a boy or a girl?

Technically, the father determines the sex of the offspring. There are two sex chromosomes: the "X" and the "Y". If an embryo has "XX", it will develop into a female, while the "XY" combination results in a male offspring.
To understand why, a little knowledge of Miosis is needed (this is the process by which sex cells are created (eggs and sperm)). Miosis is related to Mitosis, in that the end result is the creation of two cells from one. Miosis, however, ensures that half the genetic material is handed to each "daughter" cell, while Mitosis results in equal and even distribution (cock) of genetic material.
If all men are "XY" (they are), then the process is pretty straightforward: Each of the sperm must have half the normal genetic material. This means that each must have either an "X" or a "Y" chromosome. If you're a dude, 50% of the sperm will result in male offspring, and 50% will result in female. Females have two "X" chromosomes, so even when only half is replicated, there's a 100% chance an "X" is present. Everyone needs two sex chromosomes to grow, so, therefore, if 100% of the time the mom is giving an "X", and half the time the pop is shooting "X"'s and "Y"'s, it's fully the dad's genes that decide of the offspring is male or female.

Explain how the sex chromosomes determine the sex of the offspring?
it is determined by which parent give the chromosome. if the y chromosome is in it will be a girl and if it will be a boy.
What carries genes that determine the sex offspring?
Men do they are the carriers of the X and Y chromosome. Girls only have X chromosomes. Two X chromosomes mean it will be a girl and a X and a Y mean it will be a boy.
What is and example of a gene?
An example of a gene would be the X and Y chromosomes carried by the father. If the father can pass either gene to his offspring to get either a girl or a boy.
What is the natural causes of mutations?
1.)Mutations can be inherited. This means if a parent has a mutation in his/her DNA, then the mutation is passed on to the child.2.)Mutations can be acquired. This happens when a mistake accurs when a cell copies its DNA.3.)Mutations can occur by a hidden gene. This happens when your ancestor(for example, "grandma") has the mutation and that mutation is passed on to every other girl(for example), then the girl will get the mutation.
Sex-linked dominant?
DefinitionSex-linked dominant is a rare way that a trait or disorder can be passed down through families. A single abnormal gene on the X chromosome can cause a sex-linked dominant disease.Related terms and topics:Autosomal dominantAutosomal recessiveChromosomeGeneGenetic counseling and prenatal diagnosisHeredity and diseaseInheritanceSex-linked recessiveAlternative NamesInheritance - sex-linked dominant; Genetics - sex-linked dominant; X-linked dominant; Y-linked dominantInformationInheritance of a specific disease, condition, or trait depends on the type of chromosome affected (autosomal or sex chromosome). It also depends on whether the trait is dominant or recessive. Sex-linked diseases are inherited through one of the sex chromosomes (the X or Y chromosome).Dominant inheritance occurs when an abnormal gene from one parent is capable of causing disease, even though a matching gene from the other parent is normal. The abnormal gene dominates the gene pair.For an X-linked dominant disorder: If the father carries the abnormal X gene, all of his daughters will inherit the disease and none of his sons will have the disease. If the mother carries the abnormal X gene, half of all their children (daughters and sons) will inherit the disease tendency.In other words, if there are four children (two males and two females) and the mother is affected (one abnormal X, she has the disease) but the father is not, the statistical expectation is for:Two children (one girl and one boy) with the diseaseTwo children (one girl and one boy) without the diseaseIf there are four children (two males and two females) and the father is affected (abnormal X, he has the disease) but the mother is not, the statistical expectation is for:Two girls with the diseaseTwo boys without the diseaseThis does not mean that the children will necessarily be affected.
Does the male or female determine the gender in humans?
It is the x or y chromosome in the sperm of males that determine the sex of the baby. The woman carries two x chromosomes and the sperm either carries another x (a girl) or a y (a boy).
Explain how the sex chromosomes determine the sex of the offspring?
it is determined by which parent give the chromosome. if the y chromosome is in it will be a girl and if it will be a boy.
What is the name of the gene that is responsible for sexual differentiation in an embryo?
Not a single gene, whole chromosome. X and Y chromosomes determine sex. Two X chromosomes means your a girl, an X and a Y means your a boy.
What must occur for a girl to be color blind?
The girl must have a copy of the gene on each X chromosome. This means that she must have a father who is colorblind and a mother who is either a carrier or is colorblind.
What nicknames did Gene Gauntier go by?
Gene Gauntier went by The Kalem Girl.
In order for a child to inherit a recessive trait both parents must be carriers of the recessive gene?
No. A recessive gene can be inherited from one parent, a dominant from another, or two alike dominants. (No such thing as two alike recessive, the gene with the furthest back dominant gene. Say a blonde little girl has a blonde hybrid mother and a brown hybrid father. She ended up getting brown recessive. Since both of her parents were hybrid, she only had a recessive hair color gene from one parent.
Who is the blonde girl in the Gene Simmons Family Jewels episode firefighter Gene?

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.

Gene Tunney went by The Fighting Marine, and Tamer of the Tiger..
What carries the determine the sex of offspring?
Men do they are the carriers of the X and Y chromosome. Girls only have X chromosomes. Two X chromosomes mean it will be a girl and a X and a Y mean it will be a boy.
What is the probability that a woman who is a carrier of the colorblind gene and a color blind man will have a first son who will be color blind?
The probability is 0 (but the daughter will be a carrier of the color blind gene). This is because the gene dictating whether someone is color blind or not is linked to the X chromosome (and not the Y). The color blind gene is a recessive gene whilst the normal color vision gene is a dominant gene. Hence if a girl (XX) has one normal vision gene (from one parent) and one color blind gene (from the other parent), her normal vision gene will be dominant to the recessive color blind gene and hence she will have normal vision (but she will be a carrier of the color blind gene). If both her parents contribute the recessive color blind gene to her, then she will be color blind. For a woman (XX) to be color blind, she needs to be have both genes to be recessive (ie where there is no dominant normal color vision gene to dominate). For a man (XY), as long as the X gene contributed by his mother is a color blind gene, he will be color blind because he has no other X chromosome where a dominant normal color gene could reside. Hence, to answer the question, a man with normal color vision (XY, with a dominant normal color vision X gene since the gene can't be the recessive color blind gene otherwise he will be colorblind) and a colorblind woman (XX, both recessive color blind genes), will each contribute an X each the child. The man will contribute his only X chromosome which carries the normal color vision X gene and the woman can only contribute a recessive color blind gene. The man's normal color vision X gene will be dominant, and hence the daughter will definitely have normal vision (despite being a carrier).
What carries genes that determine the sex offspring?
Men do they are the carriers of the X and Y chromosome. Girls only have X chromosomes. Two X chromosomes mean it will be a girl and a X and a Y mean it will be a boy.
