How many sex chromosomes does your mother give to a normal baby........and father?
The mother and father both give a normal baby 23 chromosomes. This is because, a normal human has 46 chromosomes in all cells, except sex cells. So, a human receives half from the mother and half from the father thus 23 from each.
What is the sex determiner?
Sex is determined by the 23rd pair of chromosomes (in humans). You get an X chromosome from your mother and an X or Y chromosome from your father. If you are XX, you are female. If you are XY, you are male.
What is the chance an X chromosome is inherited from a mother?
A female has the sex chromosomes XX. Therefore they will always pass an X chromosome on to their children.
What sex chromosome does a girl obtain from her father?
Both parents will give a girl an X chromosome. The father will give a Y and the mother will give an X to a boy.
Does the y chromosome in the male sex cell have a mitochondria?
No, the Y chromosome in the male sex cell (sperm) does not have mitochondria. Mitochondria are inherited from the mother's egg cell, as they contain mitochondrial DNA. The Y chromosome carries genes that determine male sex characteristics.
How do you determine to give birth to a male?
You cannot control the sex of a fetus through determination alone. The mother donates an X chromosome via her egg. The sperm donated by the male partner, which can contain an X or Y chromosome, determines the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy (XY).http://www.science20.com/news_releases/chromosomes_are_so_20th_century_male_genes_really_determine_baby_gender_says_study#ixzz3eHLpJJRt
What are the x and y chromazones?
The Y chromosome is the male sex chromosome, but males also carry a X chromosome from their mother. XY. The female sex chromosome is the Y chromosome; YY is female. ( generally, as sex chromosome number in both sexes can vary )
How do chromosomes determine an individual's sex?
The female- or male- ness of the fertilized Ovum [Zygote] depends upon the X, or Y, 'component' of Chromosome Number 23 [the sex-chromosome] that is donated from the Male. All of the Female Chromosome Numbers 23 ARE XX.
How many sex chromosomes does your mother give to a normal baby........and father?
The mother and father both give a normal baby 23 chromosomes. This is because, a normal human has 46 chromosomes in all cells, except sex cells. So, a human receives half from the mother and half from the father thus 23 from each.
Why is genotype of the father unimportant when investigating sex-linked traits inherited by male offspring?
Fathers pass the Y sex chromosome to their sons, NOT the X sex chromosome.
What sex chromosome is present in all humans?
There are two sex chromosomes: the X chromosome and the Y chromosome. During fertilization, the mother always gives an X chromosome and the father gives either another X chromosome or a Y chromosome. Therefore, all humans have at least one X chromosome.
What is the sex determiner?
Sex is determined by the 23rd pair of chromosomes (in humans). You get an X chromosome from your mother and an X or Y chromosome from your father. If you are XX, you are female. If you are XY, you are male.
What is the chance an X chromosome is inherited from a mother?
A female has the sex chromosomes XX. Therefore they will always pass an X chromosome on to their children.
Why can only females be carriers of sex-linked genetics disorders?
This is not an entirely accurate statement, but it is generally true. It happens because sex-linked genes are located on the X chromosome only. Males have only one X chromosome (XY) and the corresponding Y chromosome from their fathers do not have genes for sex-linked traits, including color vision and proper blood clotting. If a mother has normal color vision but carries a gene for color blindness on her other X chromosome, her genotype is Cc. If she has a daughter and that daughter inherits her mother's recessive gene, it is usually balanced by her father's X chromosome if he has normal color vision, and the daughter would be Cc like her mother. However, although they are rare, a colorblind female is possible if her mother is a carrier (or is color blind, cc) and her father is colorblind also. However, a son only inherits one X chromosome, so he is totally dependent on which X chromosome his mother gives him. His father's Y chromosome, which makes him male, does not have this gene on it. The son has a 50-50 chance of inheriting his mother's color blind gene, and if he does, he will be colorblind based on the gene inherited from his female parent. His male parent donated a Y chromosome, which has no genes for this trait on it, so the mother alone determines this trait in her sons.
What is the difference between sex chromosome an autosomal chromosome?
the autosome do not control the sex organs . but the sex chromosome control the sex organs
What is the link between sex-linked disorders and sex chromosome disorders?
sex-linked is normally involving X chromosome sex chromosome normally involving Y chromosome
What sex chromosome does a girl obtain from her father?
Both parents will give a girl an X chromosome. The father will give a Y and the mother will give an X to a boy.
