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
The meaning of ALLELE is any of the alternative forms of a gene that may occur at a given locus.
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 (MULTIPLE ALLELISM), each form having a slightly different sequence of DNA bases but with the ...
The meaning of MULTIPLE ALLELE is an allele of a genetic locus having more than two allelic forms within a population.

genetic variation and inheritance patterns. They are distinct gene variants that reside at the same chromosomal locus (position). For each gene, a person receives two alleles, one from each parent. Variations of the same trait or separate traits might occur from the existence of different alleles...
What are the different forms of a gene called? They could be dominant or recessive. what types of alleles did the parents likely have, to produce the following offspring. The trait is black fur dominated to white fur A. 30 white offspring and 87 blac...

Codominance is a form of inheritance in which two different alleles for a gene are both expressed, and neither allele is dominant over the other. The alleles for type A blood and type B blood are What are the different forms of a gene called? They could be dominant or recessive. ...
