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:
A two-gene system is not inevitable. First, both mutations could occur in the same gene. Second, a single-gene sex determination, involving a gene that dominantly suppresses female function and promotes male function can be experimentally created in monoecious plants, including maize10and melon (...
aThe AMEL gene that encodes for female amelogenin is located on the X chromosome and AMEL gene that encodes for male amelogenin is located on the Y chromosome. The female has two identical AMEL genes or alleles, whereas the male has two different AMEL genes. This can be used to determine ...

Based on its allelic combination, a gene can be classified into one of three groups. These groups are: heterozygous (one dominant and one recessive allele), homozygous dominant (two dominant alleles), and homozygous recessive (two recessive alleles)....

The SNP found in the 3' UTR of the TTR gene has no effect on degrading the variant allele's expression and thus has no impact on the diminished penetrance of the trait in the Swedish population. However, the 3' UTR SNP is unique for patients descending from the Swedish founder, and thi...
Minor alleles differ from major alleles by three polymorphisms: a 74-bp duplication in intron 1 and two mutations leading to the P11L and I340M amino acid substitutions, respectively8–10. Moreover, some mutations co-segregate and functionally inter- act with the minor allele polymorphisms, ...
Despite virtually identical DNA sequences between the sexes, sexual dimorphism is a widespread phenomenon in nature. To a large extent the systematic differences between the sexes must therefore arise from processes involving gene regulation. In accordan
Briefly, SNPs were called in each population using SeqMan NGen version 1.2 (DNASTAR) and categorised as being unique to a population, on the same contig, or identical between populations. Criteria for shortlisting SNPs were good coverage (at least 8 reads in total and 3 reads or 20% for ...
