In haploid organisms every gene, irrespective of dominant or recessive and every mutation finds expression because there is only one allele for each gene in the haploid individual. Recessive allele is able to express as there is no alternative dominant allele for producing its masking effect on recessive allele.

Explanation:
Haploids are organisms that have only one set of chromosomes, which means they have only one copy of each gene. This is in contrast to diploids, which have two sets of chromosomes and therefore two copies of each gene.
In haploids, there is only one allele for each gene in the individual. An allele is one of the alternative forms of a gene that can occupy a specific position, or locus, on a chromosome. In diploids, there are typically two alleles for each gene, one inherited from each parent. However, in haploids, there is only one allele present for each gene because there is only one set of chromosomes.
Reasoning behind the answer:
Haploids are able to express both recessive and dominant alleles/mutations because there is only one allele for each gene in the individual. This means that whatever allele is present in the haploid will be expressed, regardless of whether it is recessive or dominant.
If a haploid individual carries a dominant allele for a particular gene, that dominant allele will be expressed because there is no second allele to mask its expression. Similarly, if a haploid individual carries a recessive allele for a particular gene, that recessive allele will also be expressed because there is no second allele to override its expression.
In diploid individuals, the presence of two alleles for each gene can result in masking or overriding the expression of certain alleles. For example, if an individual carries one dominant allele and one recessive allele for a particular gene, the dominant allele may mask the expression of the recessive allele. However, in haploids, there is no second allele to mask or override the expression of any given allele.
Therefore, the correct answer is option 'C' - there is only one allele for each gene in the individual.
