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.

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.

Why is it not possible for an individual to have a XY chromosomes?

About half of us DO have an XY chromosome. Males. XX chromosomes are female.


What is meant by crosswalk when working with databases?

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


How do you enter only diagonal elements in c plus plus?

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];


What causes webbed fingers?

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.
