Question

in diploid organisms, having two homologues of each chromosome can be beneficial if one allele of a gene encodes a nonfunctional protein. can haploid organisms avoid the negative effects of nonfunctional alleles?
yes, because there are two chromosomes each with a single allele that is always the same, and one can compensate for the other being nonfunctional.
no, because there is only one allele for the gene in each cell, and the nonfunctional allele has no other allele to mask it.
no, because there are two chromosomes each with a single allele that is always the same, and one cannot compensate for the other being nonfunctional.
yes, because there is only one allele for the gene in each cell, and the nonfunctional allele will be masked by another allele of a different kind.
yes, because there are always other alleles for other genes that will compensate for a nonfunctional allele.

Explanation:

Haploid organisms have only one set of chromosomes. So, for each gene, there is only one allele. In diploid organisms, if one allele is non - functional, the other allele (since there are two alleles for each gene) can sometimes mask the negative effect (e.g., in the case of dominant - recessive relationships). But in haploid organisms, there is no second allele to mask the non - functional allele.

Answer:

No, because there is only one allele for the gene in each cell, and the nonfunctional allele has no other allele to mask it.
