No, a Y chromosome must be attached to an X in order to create anything, in this case a male. Think of the X as the starting point, and you can either add another X or a Y to make a female or a male.

Yes, it is possible. A male may develop from a sperm that has not developed normally in the father. He may end up with XYY. It is rare, but it is possible.
What else can I help you with?
Ahuman can Carrie YY or YYY or XY chromosome?
Is posible that the a human can carrie YY or YYY or YYX If this is not posible, then why is not I want a explanation?
What genotype is Yy homozygous or heterozygous?
Yy is a heterozygous genotype. Homozygous would be YY or yy.
Is xx female or male?
A female is an XX. However, during development one of the X chromosomes is deactivated and is called a Barr body.Human females have XX sex chromosomes. A male has XY chromosomes. The Y chromosome is very small and contains only genes that make a male a male.
Which sexx chromosomes do males have?
Y chomozomes, I think. It says on Wikipedia.
What is the biological sex of an individual with XY sex chromosomes in humans?
The biological sex of an individual with XY sex chromosomes in humans is typically male.
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.
Ahuman can Carrie YY or YYY or XY chromosome?
Is posible that the a human can carrie YY or YYY or YYX If this is not posible, then why is not I want a explanation?
What is meant by xx xy yx yy?
These letters represent the four possible combinations of alleles for a gene located on the X and Y chromosomes. In genetics, "XX" represents a female with two X chromosomes, "XY" represents a male with one X and one Y chromosome, "YX" does not have a genetic meaning, and "YY" is not a valid combination as males cannot have two Y chromosomes.
What is the phenotype for XY?
xy chromosomes mostly fall on male gender.
Are XY male or female?
male
What does the XY in Kyle XY stand for?
The male chromosome
How many chromosomes are there in sex cells and why?
22 pair of autosomes and 1 pair of sex chromosomes. A male determines the sex with XY chromosomes and the female only has YY. 23; half of the normal 46 for a cell. This is so when the male and female cells meet, they will form a normal 46-chromosome cell.
What is the genotype of a male and female?
These genotypes are determined by a human's 23rd pair of chromosomes. If the subject is female, she has two X's reading XX. If it is male, then his genotype will read XY. There is a 50-50 shot of each. This is because a woman donates one chromosome (she only has two X's so it is inevitable that she will donate an X), and a man donates one of his. If a man donates his 'X' then there will be two X's and the child will be female. If he donates his 'Y' then the child will be male.Male is XY, female is XX. There are, however, other genotypes (XXY, XXX, XO...) and not all people have a phenotype that goes with their genotype.
YY for me YY you see I see you be YY for me What does this mean?
Are referring to the YY chromosome, meaning you are male, the person you're looking at is male, and 'he is for you' meaning you want a 'hook up'.The correct answer is that the Rhyme is actually an old riddle and it goes...2Ys UR2Ys UBIC UR2Ys 4 MeIt means...Too wise you areToo wise you beI see you areToo wise for me.
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 )
What is xy?
male sex chromosome
What is a genotype of a human male?
XY
