Animals avoid inbreeding only rarely. [2] Inbreeding results in homozygosity which can increase the chances of offspring being affected by recessive traits. [3] In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population [4] [5] (called inbreeding depression), which is its ability to survive and ...

[2] [3] In most species with XY sex determination, an organism must have at least one X chromosome in order to survive. [4] [5] The XY system contrasts in several ways with the ZW sex-determination system found in birds, some insects, many reptiles, and various other animals, in which the heterogametic sex is female.
In X-linked recessive disorders, only females can be the carriers of the recessive mutation, making them obligate carriers of this type of disease. Females acquire one X-chromosome from their father and one from their mother, and this means they can either be heterozygous for the mutated allele or homozygous. If heterozygous, she is a carrier ...
U.S. officials on Thursday approved drugmaker BioMarin's gene therapy for the most common form of hemophilia, a $2.9 million infused treatment that can significantly reduce dangerous bleeding ...
In human, the F9 gene is located on the X chromosome at position q27.1. Because the gene for factor IX is located on the X chromosome (Xq27.1-q27.2), loss-of-function mutations thereof are X-linked recessive: males experience the disease phenotype much more frequently than females
