They get Klinefelter syndrome. They have male sex organs, but the testes are abnormally small and the man is sterile. Even though the extra X is inactivated, some breast enlargement and other female body characteristics are common.

∙ 10y agoA male with an extra X chromosome has Klinefelter's syndrome - and is a 47XXY male. Such males show both traits of males and females during puberty - that is, both the gonads develop, but not completely.

What chromosome tells us the sex of a human?
The X and Y sex chromosomes. If the embryo inherits an X and Y chromosome, it will be male. If the embryo inherits two X chromosomes, it will be female.
Why does a sex-linked trait only require one recessive allele on the X chromosome of a male to show the phenotype?
because the male only inherits one X chromosome (from his mother), his other sex chromosome is Y (from his father)
What is klien felter's syndrome?
Klinefelter's syndrome occurs when an extra x chromosome shows up in a male or an extra y show up in a female. Principal effects include hypogonadism and sterility.
Who does a male child inherit his X chromosome from?
yes, some people have xxy chromosomes, a genetic mutation. Although I'm not sure if the extra chromosome is from the fathers sperm or sex cell. Hope this helps :)
What does a person with an X chromosome and a Y chromosome have?
male

What chromosome is klinefelters syndrome located on?
they have a extra chromosome, a normal male is XY, a male with klinefelters is XXY.
Why does a sex-linked trait only require one recessive allele on the X chromosome of a male to show the phenotype?
because the male only inherits one X chromosome (from his mother), his other sex chromosome is Y (from his father)

What is Y chromosomes?
A Y Chromosome is a mammalian sex chromosome which occurs only in male cells.
Why x-linked recessive more frequent in male in mammal?
A male inherits only one X sex chromosome, so whatever alleles are on that chromosome will be expressed. A female inherits two X sex chromosomes, so there is a possibility that she will inherit at least one dominant allele for a trait, in which case she will have the dominant trait.
Who does a male child inherit his X chromosome from?
yes, some people have xxy chromosomes, a genetic mutation. Although I'm not sure if the extra chromosome is from the fathers sperm or sex cell. Hope this helps :)
Is klinefelter syndrome chomosomal mutation?
Klinefelters syndrome occurs in a male and it is when they carry and extra X chromosome having a total of 47chromosomes rather than the usual 46. Thus resulting in a chromosomal mutation.
What do you call a male that inherits something?
A male beneficiary.
Is it true that a person who inherits two X chromosomes will be a male?
Answer:This is not true. If you inherit two X chromosomes you will be a girl. A boy has a X and a Y chromosome. I don't know for sure, but I think so. After all, the numbers xs are greater than ysAnswer:No, it isn't. A person with XY chromosomes is male. Two X chromosomes is female.Answer:It is possible but they have to inherit a Y chromosomes. It called Klinefelter's syndrome (KS). KS has two X chromosomes and one Y chromosome. They can grow breast and have an ovary and have anger problems. Most men like this in up in prison.
Is Klinefelter Syndrome sex-linked or autosomal?
Klinefelter Syndrome is sex-linked, because it is a genetic defect that results in a male having an extra X chromosome.
In humans an individual inherits one copy of each homologous chromosome from each parent In turn one of each homologous pair goes to a gamete to be passed on Females inherit two X chromosomes and male?
AnswerBoys must inherit the Y chromosome from their father.
