Is YY possible?
Males withXYY syndrome
XYY syndrome is a genetic condition in which a male has an extra Y chromosome. There are usually few symptoms. These may include being taller than average, acne, and an increased risk of learning disabilities. The person is generally otherwise normal, including typical rates of fertility.

Is there a YY gender?
The X and Y chromosomes, also known as the sex chromosomes, determine the biological sex of an individual: females inherit an X chromosome from the father for a XX genotype, while males inherit a Y chromosome from the father for a XY genotype (mothers only pass on X chromosomes).What would happen if you had YY chromosomes?
XYY syndrome is a genetic condition in which a male has an extra Y chromosome. There are usually few symptoms. These may include being taller than average, acne, and an increased risk of learning disabilities. The person is generally otherwise normal, including typical rates of fertility.Is it possible to have only 2 Y chromosomes?
Males normally have one X and one Y chromosome. However, individuals with this syndrome have one X and two Y chromosomes. Affected individuals are usually very tall. Many experience severe acne during adolescence.Can you be born with YY chromosomes?
This condition is also sometimes called Jacob's syndrome, XYY karyotype, or YY syndrome. According to the National Institutes of Health, XYY syndrome occurs in 1 out of every 1,000 boys. For the most part, people with XYY syndrome live typical lives.Is a YY chromosome possible?
What causes Superfemale?
Although triple X syndrome is genetic, it's usually not inherited — it's due to a random genetic error. Normally, people have 46 chromosomes in each cell, organized into 23 pairs, including two sex chromosomes. One set of chromosomes is from the mother and the other set is from the father.Can an XY female get pregnant?
Here's the bottom line: pregnancy requires a uterus. Males and most XY females cannot become pregnant because they don't have a uterus. The uterus is where the fetus develops, and pregnancy isn't possible without it. In most cases, having a Y chromosome means having no uterus, so pregnancy isn't possible.What is Superman syndrome?
The Superman syndrome occurs when males receive an extra Y chromosome at conception, creating an XYY combination. This results in a male baby born with the XYY syndrome, which is a random occurrence due to the sperm cell's formation before conception occurs.Why YY chromosome is not possible?
This means that genes on the Y chromosome cannot undergo genetic recombination, the “shuffling” of genes that occurs in each generation which helps to eliminate damaging gene mutations. Deprived of the benefits of recombination, Y chromosomal genes degenerate over time and are eventually lost from the genome.Why is yy not viable?
Originally Answered: Why is genotype (XX) viable while genotype (YY) isn't? The X chromosome contains a lot of genes, many of which are vital. The Y chromosome is very small, and contains only a few genes, necessary for the male phenotype. Therefore, the YY genotype is not viable.Can a man have only Y chromosomes?
Typically, biologically male individuals have one X and one Y chromosome (XY) while those who are biologically female have two X chromosomes. However, there are exceptions to this rule. The sex chromosomes determine the sex of offspring.Can humans have 47 chromosomes?
Humans have 23 pairs of chromosomes. A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.Why is it called Jacob's syndrome?
This syndrome is named after Patricia Ann Jacobs, who was the first person to discover the disease and for which she received many awards in recognition of her discovery. Jacob's syndrome or XYY syndrome is a chromosomal disorder resulting from an extra X chromosome in males. It is also called XYY karyotype.What XXY called?
Klinefelter syndrome (sometimes called Klinefelter's, KS or XXY) is where boys and men are born with an extra X chromosome.Can females have Y chromosome?
Each person normally has one pair of sex chromosomes in each cell. The Y chromosome is present in males, who have one X and one Y chromosome, while females have two X chromosomes.How are intersex born?
The person has the chromosomes of a woman, the ovaries of a woman, but external (outside) genitals that appear male. This most often is the result of a female fetus having been exposed to excess male hormones before birth.Can a woman carry the Y chromosome?
The X and Y chromosomes are called “sex chromosomes” because they contribute to how a person's sex develops. Most males have XY chromosomes and most women have XX chromosomes. But there are girls and women who have XY chromosomes. This can happen, for example, when a girl has androgen insensitivity syndrome.What happens if you have 48 chromosomes?
Description. 48,XXXY syndrome is a chromosomal condition in boys and men that causes intellectual disability, developmental delays, physical differences, and an inability to father biological children (infertility). Its signs and symptoms vary among affected individuals.What is Metafemale syndrome?
Triple-X syndrome occurs in women who inherit three X chromosomes--their genotype is XXX or more rarely XXXX or XXXXX. As adults, these "super-females" or "metafemales" , as they are sometimes known, generally are an inch or so taller than average with unusually long legs and slender torsos but otherwise appear normal.Can you change your XY chromosomes?
An individual with one X and one Y sex chromosome will usually have male body parts. It is the presence of this Y chromosome that determines a person's biological sex. Whatever set of chromosomes a person has when they are born cannot be changed. This is because chromosomes are in all the cells that make up our bodies.How many sexes are there?
Based on the sole criterion of production of reproductive cells, there are two and only two sexes: the female sex, capable of producing large gametes (ovules), and the male sex, which produces small gametes (spermatozoa).How many chromosomes did Jesus have?
Being fully human, Jesus had normal appearing human chromosomes - so a paired set of 22 autosomes and an X and Y (note that Dylan refers to “alleles” in his question. Alleles are forms of genes that are contained on chromosomes). Anything else wouldn't make sense when one considers that he was fully human.Can you have 50 chromosomes?
These findings show that initial hyperdiploidy (greater than 50 chromosomes) is an independent favorable prognostic sign in childhood ALL and additional chromosomal structural abnormalities may not indicate a poor prognosis among childhood ALL with hyperdiploidy (greater than 50 chromosomes).What is Tetrasomy?
Tetrasomy 18p is a chromosomal condition that affects many parts of the body. This condition usually causes feeding difficulties in infancy, delayed development, intellectual disability that is often mild to moderate but can be severe, changes in muscle tone, distinctive facial features, and other birth defects.
