YY chromosomes?

Question

XY chromosomes are for male, XX are for female, if possoblie(just imagine) what would YY give?

I didint ask if its possible... i asked what would the result be...

ok, so lets get more specific, the x chromosome is the so called female chromosome, the Y is male, males have XY, and have some female characteritics, nipples and the like.... things that we have no use for, what if there was somebody with YY, would he be without nipples and the like.... im not asking if its possible(i know its not)

damn! i think i just starred my own question! is that even suppose to happen?

Answer 1

This is impossible, because the man that who is XY only has one Y chromosome to give. Which would mean the child would have to be XX or XY.

Answer 2

It is not possible. The Y chromosome does not have a full complement of genes that the X chromosome contains. An individual must have at least one X chromosome to live.
There are several genes on the X chromosome that cause disease when deleted, such as the genes for Haemophilia, Menkes syndrome, familial Leukodystrophy, and several others genes that are homozygous lethal, i.e. at least one copy is required for the person to survive. An embryo without any X chromosomes would not have any copies of any of these genes, and would die early in development.

There are individuals with three of sex-chromosomes: XXY (Klinefelter's Syndrome) individuals are male with abherent female characteristics and are ususally sterile; XYY are male and may show increased aggression; and XXX (triple X syndrome) are female and may show slight retardation (even though the scientific results are inconclusive, the XYY and XXX syndromes have been the subjects of much political debate by people trying to prove that all men are killers and all women are stupid). There are also individuals with only one sex-chromosome: X0 (Turner's syndrome) individuals are female with various minor developmental defects and are usually sterile; Y0, like YY, is inviable.

XYY-trisomy does exist It is a relatively common human sex chromosome anomaly in which a male has two Y chromosomes rather than one. It occurs in 1 in 500–1,000 live male births, and individuals with the anomaly are often characterized by tallness and severe acne and sometimes by skeletal malformations and mental deficiency. It has been suggested that the presence of an extra Y chromosome in an individual may cause him to be more aggressive and prone to criminal behaviour, a condition called the “supermale” syndrome. Studies of prison populations have tended to confirm this hypothesis; but subsequent studies of the general population, especially those in which affected individuals were observed from early childhood over a long period of time, have cast serious doubt on the validity of linking the chromosomal anomaly directly to behavioral abnormalities.

Answer 3

It would be impossible in the human XY system, but in *other* systems, such as the fruitfly, your gender is decided by the dosage of the sex chromosomes (more "x"=female, more "y"=male, equal x and y=female) so your critter would be MALE.

As for the actual secondary sexual characteristics, they are actually not decided just by the X and Y chromosome, which is why we see people with XXY who are male, and XXY who are female.
More than just a missing X would be needed to get no nipples, etc. (If it were viable, but it isn't, but you said imagine...)

Answer 4

it is practically impossible for a male to have the sex chromosomes yy because every male has the chromosomes of XY one passed from the mother (X) and one from the father (Y or X) so if the Y chromosome is passed you get XY it is impossible to have YY unless something EXTREMELY CREEPY HAPPENED but if it did happen it would pass down y IF IT REALLY HAPPENED!!!

Answer 5

The YY katyotype is not viable. Too many essential genes are on the X chromosome.

Answer 6

THIS IS COMMON SENSE

The answer is a YY cannot occur because there would be no egg to fertilize, The egg is always an X and it is required for a pregnancy so not fertilization would occur. Its common sense because a woman cannot have a child without an egg

THINK YY would be TWO SPERM

Answer 7

no ıt is not because women don't have any y chromosomes one chromosome comes from a man and one of woman for a baby. a women don't have any y chromosome. ıf two men could give birth a baby they could make xy

Answer 8

If it happened , you d create a titan.Zeus the 3rd

Answer 9

what.... i don't understand it... maybe two males in the same body.. how can that be...
