There are 22 autosomal chromosomes and 2 sex chromosomes in humans. In all the other chromosomes, the homologous pairs match up genetic loci. However, in human sex chromosomes the X and Y chromosome are different (with the X chromosome being much larger and the Y chromosome carrying genes that cause "maleness").
Someone with an X and a Y chromosome is a male because he has a Y chromosome that carries the genes that code for "maleness". Females "lack" this Y chromosome, and thus show characteristic female phenotypes.
XX are the sex defining chromosomes for a girl and XY for boys
xx and xy are the chromosomes of the male and female body. the female has xx chromosome and the male has xy chromosomes the sex determination chromosomes
An xx and an xy cell are used to denote female and male zygotic cells, respectively. They are formed from the union of a female x egg and a male x or y sperm.
XX and XY is the male-female cross in humans and some other organisms. XX= female, XY= male.
XX is for women, XY is for men. The letters don't stand for any word.
XX are the female chromosomes and XY are the male chromosomes.
xx means a girl xy means a boy
About half of us DO have an XY chromosome. Males. XX chromosomes are female.
Also referred to as a schema crosswalk, when someone talks about a crosswalk, what they are generally talking about is a table that allows for references to be built that allow the way data is stored in one database to be matched up with data in another database. For instance, let's say a school district's student database software keeps track of the gender of each student with a single character field that codes females with an "F" and males with an "M". The school district is required to upload data about their students to the state in which it operates for analysis, but the state wants to see males coded as "XY" and females coded as "XX". A crosswalk would need to be created that would convert the gender data in the export process. The crosswalk may look something like this: F -- XX M -- XY
Matrices have two diagonals: main diagonal and anti-diagonal. The main diagonal runs from top-left to bottom-right. For square matrix A: // main diagonal: for (size_t xy=0; xy<A.size(); ++xy) cin >> A[xy][xy]; // anti-diagonal for (size_t x = A.size()-1, y=0; y<A.size(); --x; ++y cin >> A[x][y];
Doctors call this condition syndactyly. Webbed fingers or toes can be part of Turner's Syndrome, which is a chromosomal disorder that affects only females. It involves the absence of all or part of one of the sex chromosomes. Normal female chromosomes are expressed as XX. In Turner's Syndrome, the sex chromosomes are expressed as XO, to indicate that there is a chromosome missing. More commonly though, syndactyly is caused by a genetic defect, and is therefore found to run in families. It is found in both males and females who have the normal arrangement of sex chromosomes: XX for females; XY for males. There are five different types of syndactyly which are classified according to which fingers or toes are involved. This condition can be corrected by surgery, which often involves a small skin graft from another part of the body. With the milder types of syndactyly, surgery can be considered elective (that is, not strictly necessary.) However, when fusion of the fingers or toes is extensive, or when the fusion will cause deformity as the fingers and hands grow, surgery is necessary.
An input device. It is because it let the source to flow.
xx and xy genetic mutation.
XX or XY are the combination of geanes for reproduction process in humen being. Whereas XX is the genetic representation of a female and XY being of a male. The genes XX & XY appear in the 23rd pair of chromosomes in the karyotype of a human.
By textbook, the genetic coding in every cell in a human's body should be exactly the same. So, yes, all females have the XX chromosomes in every cell of their body. Males will have the XY chromosome in every cell of their body.
In humans, gender is determined by the x and y chromosomes, with xx being a genetic female and xy being a genetic male
XX for female and XY for male. -anonymous18_K
It is referring to the male chromosome whereas the the female gender chromosome is XX.
Yes, but unlike with mammals, in the case of birds females have XY, and males have XX. With mammals like us males have XY and females have XX.
The female has xx and the male has either xx or xy
Because in males they have only 1 X chromosome. The other one is Y. But in females they have 2 XX chromosomes so the chance that X chromosome will carry disease to cause illness is lower. Example: lets say xx (recesssive) phenotype makes illness, whereas XX (dominant) is healthy. A woman can have XX, Xx, xx right? Since Xx is a carrier and XX is healthy you wont see the illness. only xx can make illness. 1/3 chances she is sick. However in males they have XY. so he can only have either XY or xY. No carrier form is present. The chances he will be sick is %50. got it? Im a genetic engineer and molecular biolog so count on me :)
XX XY - 2002 is rated/received certificates of: Germany:16 UK:15 USA:R
Sperm is X or Y, it fertilizes the egg forming XY or XX. XY would be male and XX female.
