Noun
/ɛks ˈkrɒməsəʊm/
The X chromosome is one of two sex chromosomes in many organisms, including humans. It plays a critical role in determining an individual's sex, being one of the two chromosomes (the other being the Y chromosome) responsible for male and female biological characteristics. The presence of two X chromosomes typically results in a female (XX), while one X and one Y chromosome result in a male (XY).
In the context of genetics and biology, "X chromosome" denotes both the specific chromosome and its associated genes, which may influence traits and inherited conditions. It is typically used in scientific and medical discussions.
The term "X chromosome" is frequently used in both written and oral contexts, particularly in discussions related to genetics, biology, and medicine.
The X chromosome carries many genes that are vital for normal development.
(El cromosoma X transporta muchos genes que son vitales para el desarrollo normal.)
Women inherit one X chromosome from each parent, resulting in two X chromosomes.
(Las mujeres heredan un cromosoma X de cada padre, lo que resulta en dos cromosomas X.)
Certain genetic disorders are linked to mutations on the X chromosome.
(Ciertos trastornos genéticos están vinculados a mutaciones en el cromosoma X.)
The phrase "X chromosome" is not commonly part of idiomatic expressions in English, but related phrases may arise in scientific discussions or popular culture when addressing gender and genetics.
Here are some idiomatic expressions related to chromosomes and gender:
"Crossing chromosomes"
She always jokes about crossing chromosomes when discussing the different characteristics of her daughters.
(Ella siempre bromea sobre cruzar cromosomas al hablar de las diferentes características de sus hijas.)
"X-linked"
Many scientists are focusing on X-linked disorders to develop new treatments.
(Muchos científicos se están enfocando en los trastornos ligados a X para desarrollar nuevos tratamientos.)
"Carry the X"
In our family, many men carry the X for color blindness, which makes it a common trait.
(En nuestra familia, muchos hombres llevan el X para el daltonismo, lo que lo convierte en un rasgo común.)
The term "X chromosome" derives from the 20th century, with "X" first used in 1891 by German scientist Hermann Henking, who referred to one of the sex chromosomes in insects as "X". The name was later adopted in the context of human biology as research advanced in genetics.
This comprehensive breakdown covers the term "X chromosome" and its relevance across various contexts and disciplines.
