What chromosomes did father contribute if a normal female is produced?
The father must have contributed an X chromosome if a normal female is produced.
Which sex chromosome does a father pass on to a son?
A father passes on his Y chromosome to his son. In humans, males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). Therefore, the son inherits the Y chromosome from his father and an X chromosome from his mother, resulting in a male (XY) offspring.
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.
Why can't a female inherit a gene found on the y chromosome?
Females do not have a Y chromosome, so they cannot inherit genes found on it. The Y chromosome is passed down from father to son, and females inherit two X chromosomes, one from each parent. Therefore, any gene found on the Y chromosome is not present in females.
Which gamete determines the gender of the young?
In humans females are homogametic and males are heterogametic. It is the male biological parent who contributes the sex chromosome that determines the sex of any child.Human females are XX and all their ova carry an X chromosome. Females always give their children an X chromosome.Human males are XY and half their spermatozoa carry an X chromosome and half carry a Y chromosome. Depending on the sex chromosome in its biological father's spermatozoon, a child receives an X or a Y chromosome from its biological father.If a child receives an X chromosome from its father she will be XX and a girl. If a child receives a Y chromosome from its father he will be XY and a boy.
What type of DNA only is transmitted by fathers to sons?
The DNA of the Y-chromosome is the DNA that is transmitted only from father to son. This is because women have two X-chromosomes, one of which is given to each child. But men have one X-chromosome and one Y-chromosome. So if a father gives a Y-chromosome to his child that child will be male, while only females receive the father's X-chromosome.
Y linked genes are passed only from who?
Y-linked genes are only passed from father to son because the Y chromosome is inherited exclusively in a paternal manner. Since females inherit an X chromosome from each parent, they do not receive a Y chromosome from their father.
What chromosome has to be present for a mother to have a male child?
A mother needs to contribute an X chromosome to her child for them to be male. The father contributes a Y chromosome, resulting in an XY chromosome pair which determines a male child.
The body cells of human males have what two chromosomes?
The body cells of most humans have 46 chromosomes, which can be arranged into 23 pairs. One chromosome in each pair comes from the mother and the other chromosome comes from the father. Of the 23 pairs, 22 pairs (the body chromosomes, or autosomes) are the same in males and females. The 23 rd pair, called the sex chromosomes, is different in males and females. In females, the sex chromosomes are the same and are called X chrosomes. In males, the sex chromosomes are different. One is an X chromosome (inherited from your mother or your father) and the other is a smaller chromosome called the Y chromosome (inherited from your father). So, the two chromosomes which are found in human males (but not human females) are the sex chromosomes, X and Y. See: http://biology.about.com/library/weekly/aa091103a.htm
