x-linked recessive inheritance
Noun: - A hereditary pattern in which a recessive gene located on the X chromosome results in the manifestation of the characteristic in male offspring and a carrier state in female offspring. This pattern of inheritance is specific to genes found on the X chromosome. Males, having only one X chromosome, will express the trait if their single X carries the recessive allele. Females, having two X chromosomes, will typically only be carriers if they possess one recessive allele, as the dominant allele on their other X chromosome usually prevents expression of the recessive trait.
This term is used in the fields of genetics, biology, and medicine to describe a specific mode of genetic transmission. - Hemophilia A is a classic example of X-linked recessive inheritance. - Genetic counselors explained the principles of X-linked recessive inheritance to the family.
- "to follow a pattern of X-linked recessive inheritance": Describes a trait or disorder that is passed down according to this genetic rule.
- Color blindness often follows a pattern of X-linked recessive inheritance.
- X-linked (adj): Referring to a gene located on the X chromosome.
- Duchenne muscular dystrophy is an X-linked disorder.
- Sex-linked inheritance (n): A broader category of inheritance for genes located on sex chromosomes (X or Y).
- Carrier (n): An individual, typically female in this context, who has one copy of a recessive allele and does not show the trait but can pass it to offspring.
- X-linked recessive trait
- Sex-linked recessive inheritance (Note: This is often used synonymously, though technically it is a broader term that could also refer to genes on the Y chromosome).
- Manifest in males: A common phrase describing the outcome of this inheritance pattern.
- Due to X-linked recessive inheritance, the condition manifests in males.
- Carrier female: A standard term for a female who carries one copy of the recessive allele.
- The mother was identified as a carrier female for the trait.
