A. 0.2 B. 0.4 C. 0.6 D. 0.8 相关知识点: 试题来源: 解析 B。解析:在基因频率计算中,等位基因频率之和为1。已知A的频率是0.6,那么a的频率就是1 - 0.6 = 0.4。从语法方面,这是一个一般现在时的数学计算与生物知识结合的题目。反馈 收藏
Alleles are different versions of the same gene. In other words, alleles are different forms of a gene that arise due to mutations or changes in the DNA sequence of the gene. These mutations can occur spontaneously, or they can be inherited from parents...

Alleles usually occur in pairs, one on each HOMOLOGOUS CHROMOSOME in a DIPLOID cell nucleus. When both alleles are the same the individual is described as being a HOMOZYGOTE; when each allele is different the individual is a HETEROZYGOTE. The number of allelic forms of a gene can be many (...

What are the different forms of a gene called? They could be dominant or recessive. What are all of the alleles in all the individuals that make up a population called? What is the difference between an organism?s genotype and its phenotype?
The meaning of ALLELE is any of the alternative forms of a gene that may occur at a given locus.
Multiple allelesare more than two alternate forms of a gene that exist within a population. This means that there are more than two possible versions of a particular gene in the gene pool of a population, and each individual can carry at most two of these alleles. ...
Class I HLA alleles (alternative forms of a gene) are associated with CD8+ T cells, and their allele-specific sequence information is available at the IMGT/HLA database. The available sequences are one-dimensional (ID), and the peptide-binding functional inference often requires 3-dimensional ...
However, for instance the same ebony mutation has about ten different forms, all of them initiated by a mutation in one locus. 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 ...
