female
x and y
Generally, since the sex determining region is on the Y chromosome, this person is male. The SRY is a gene control area that determines male sex. Female is the default body plan in humans; males are made.
The 23rd pair in a karyotype shows if it will be male or female
The 23rd pair of chromosomes that differ in males and females is called the sex chromosomes. In females, the 23rd pair consists of two X chromosomes (XX), while in males, it consists of one X and one Y chromosome (XY).
The 23rd pair of chromosomes are the sex chromosomes. In female humans, both sex chromosomes are homologous, and characterized as XX. In male humans, one sex chromosome is an X chromosome and the other is a much smaller, nonhomologous Y chromosome, and is characterized as XY.
No, 22 pairs of chromosomes are autosomes. The last, or 23rd, pair are sex chromosomes.
The 22nd pair of chromosomes is determined by the combination of one chromosome from each parent during fertilization. Each parent contributes one chromosome to determine the genetic makeup of the 22nd pair.
Each human normally has 46 chromosomes separated into 23 pairs. In males, the 23rd "pair" is not really a pair since males have an X and a Y sex chromosome.
Both X and Y chromosomes i.e. Allosome 23rd pair contains sex linked genes.
All Human Body Cells, also called somatic cells, have 46 chromosomes. These 46 occur is 23 pair. The first 22 pair are called autosomes. The 23rd pair are the sex chromosomes, xx for female, xy for male.
Nondisjunction -Trisomy 21(Down Syndrome) means there are 3 chromosomes on the 21st pair of chromosomes. -Kleinfelters (XXY) means there is an extra chromosome on the 23rd pair(where the sex chromosomes lie). -Turner Syndrome(XO) On the 23rd pair, there is no Y or second X chromosome. The female can survive with this.
Chromosomes are arranged in pairs and they are not yet named, but each of the pair is identified by numbers 1 to 22 (ie., twenty-two pairs of autosomes) and the 23rd pair by xx (in females) or xy (in males) to represent gonosomes (sex chromosomes).
