haploids are better for mutation studies because in them all the mutations whether recessive or dominant are expressed as_______________?
Correct answer: C. There is only one alleles of each gene present in each cell
- A. There are many alleles of each gene in each call
- B. There are two alleles of each gene in each cell
- C. There is only one alleles of each gene present in each cell
- D. Non3e4 of the above
Explanation
A haploid cell has only one allele of each gene, so a mutation cannot be hidden by a second normal allele and is expressed whether it would be called dominant or recessive in a diploid. Thus option c supplies the reason haploids are useful in mutation studies.
