- 中国大学MOOC: Recessive alleles form no gene products, and thus are not expressed.
- A________ trait is opposed to a recessive trait which is expressed only when two copies of the gene are present. A: determinant B: dormitory C: dominant D: dormant
- Some genes can be expressed in different ways to generate multiple gene products from a single segment of DNA.
- If a particular trait had a gene that had a possibility of 9 alleles in the population of a species, which of the following is true regarding this gene? A: The diploid number for the alleles would be 18 for this organism. B: The haploid number for the alleles would be 9 for htis organism. C: The maximum number of alleles for this gene would be 2. D: There is infinite variety in the expression of this trait in one organism.
- Control of gene expression<br/>by preventing a gene from being expressed. () A: Transcription B: Induction C: Translation D: Replication E: Repression
