An x chromosome is specifically a feminine chromosome. With a x and y chromosome its male, with a x and x, it is a female.
chromosome 1 chromosome 1
No, there are 46 chromosomes in one cell. A gamete, or sex cell, has 23 chromosomes because during fertilization, the female and male gametes (egg and sperm, respectively) come together to form a new cell with 46 chromosomes
Chromosome # + pso the short arm of Chromosome 11 is referred to as 11p
No. An 'X' chromosome looks like an 'X'. The 'Y' chromosome looks like a deformed 'X'. It is noticeably different to an 'X' chromosome. Also, the 'Y' chromosome is only a third of the size of an 'X' chromosome - an 'X' chromosome is 155 million base pares, while the 'Y' chromosome is only 58 million base pairs.
Deletion: Part of a chromosome is missing. Duplication: A segment of a chromosome is copied multiple times. Inversion: A segment of a chromosome is reversed in orientation. Translocation: Part of a chromosome breaks off and attaches to another chromosome.
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18
The gene that causes cystic fibrosis is located on chromosome 7, which is an autosome, not a sex chromosome.
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
There are two sex chromosomes: the X chromosome and the Y chromosome. During fertilization, the mother always gives an X chromosome and the father gives either another X chromosome or a Y chromosome. Therefore, all humans have at least one X chromosome.
The X Chromosome.
