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:

Cancer development is, in many cases, associated with a change in allele number. Several genetic diseases are caused by haploinsufficiency: Lack of one of the alleles or its improper functioning. In the paper we consider the stochastic expression of a gene having a variable number of copies. ...

1. Identify the Alleles: The alleles for the gene I are IA, IB, and IO. Here, IA and IB represent the alleles for blood groups A and B, respectively, while IO represents the allele for blood group O. 2. Understand Dominance: According to the information given, IA and IB are dominant...
B and O were discovered by Landsteiner while blood group AB was discovered by de Castello and Steini . Alleles are an alternative form of a gene. There are two types of alleles, dominant and recessive or wild and mutant types. Mendel found only two forms of the...

In this case there exists a whole series of alleles for a given gene, that is, a gene can be in several states. They are known as multiple alleles of a given gene (or of a locus, where the given gene is localized). Note that theoretically the case of multiple alleles is similar to...
