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.
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.
What is and example of a gene?
An example of a gene is the BRCA1 gene, which is known for its role in hereditary breast and ovarian cancer. This gene provides instructions for making a protein that helps repair damaged DNA and maintain the stability of the cell's genetic material. Mutations in the BRCA1 gene can increase the risk of developing certain types of cancer.
A girl is a hemophiliac whose mother is normal what are the genotypes of her parents?
The girl must have inherited an X chromosome with the hemophilia gene from her mother, who is a carrier (heterozygous X^HX^h). The father must have contributed a Y chromosome, as males determine the offspring's sex. The father's genotype is not directly related to the daughter's hemophilia status.
Explain how the sex chromosomes determine the sex of the offspring?
The sex chromosomes inherited from the parents determine the sex of the offspring. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of a Y chromosome results in the development of male characteristics, while the absence of a Y chromosome leads to the development of female characteristics.
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).
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.
What is the name of the gene that is responsible for sexual differentiation in an embryo?
The gene responsible for sexual differentiation in embryos is called the SRY gene (Sex-determining Region Y). This gene is located on the Y chromosome and is crucial for the development of male characteristics in individuals.

What nicknames did Gene Tunney go by?

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 is the name of your parent's sisters?
Your parent's sisters are your aunts. You are their niece if you are a girl, or their nephew if you are a boy.
Who is Alice Coachman parent?
boy 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.
