In the study of genetics, alleles are different forms of a gene. If a gene has two alleles, A and a, and the frequency of allele A is 0.6, what is the frequency of allele a? A. 0.2 B. 0.4 C. 0.6 D. 0.8 相关知识点:
1998). These forms of EDS are inherited in an autosomal dominant fashion, but new mutations are common. The altered mechanical properties of skin and ligaments made alterations in the constitutive “collagen” a strong candidate(s) for the location of the basic defect (Grahame and Beighton 1969...

However, limited sampling left unknown whether the same genes are generally (re)used and what is the evolutionary source of the selected alleles, i.e. leaving unresolved the evolutionary dynamics and mechanism underlying these striking adaptations. We ask specifically: (1) Does gene-level ...
Purpose:To date, of all the genes studied in relation to age-related macular degeneration (AMD), the alleles of the apolipoprotein (apoE) gene have been the most consistently associated with disease. However, not all apoE studies have found an association, and among these the associations differ...
. Adding complexity to this expression pattern, there are two alternate splice forms of SHIP, and the levels of these splice forms also change during hematopoiesis 38., 39.. As well, C-terminal truncations of SHIP have been identified in non-ionic detergent solubilized cell lysates that may ...

Exome-sequence analysis identifies rare alleles associated with BMI To identify rare variants associated with adult BMI, we performed an ExWAS using genotype and phenotype data from 419,668 individuals of European ancestry from UK Biobank13. Individual gene-burden tests were performed by collapsing ra...
Short H2A (sH2A) histone variants are primarily expressed in the testes of placental mammals. Their incorporation into chromatin is associated with nucleosome destabilization and modulation of alternate splicing. Here, we show that sH2As innately possess features similar to recurrent oncohistone mutation...
