How do scientists find their way around a chromosome? With chromosome maps called idiograms, researchers can pinpoint the locations of genes and locate abnormal gene forms. Aa Aa Aa Most ...

Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs. Each chromosome in a pair carries the same types of genes. The 23rd pair are the sex chromosomes: In females ...

The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the biological sex, reproductive organs, and sexual characteristics that develop in a person.

Some mutations can affect the structure of one or more chromosomes - these are chromosome structure mutations.

In mammals, female (XX) and male (XY) cells exhibit sex chromosome dimorphism. To achieve dosage compensation of X-linked ...
