Haploid

Vedclass · Answer

(D) Most mutations are recessive and harmful. In a $Haploid$ organism,there is only one set of chromosomes,meaning there is no second allele to mask the effect of a mutant allele. Therefore,any mutation that occurs in a $Haploid$ organism is immediately expressed in the phenotype. If the mutation is harmful,it will have a direct and significant negative impact on the organism's survival. In contrast,in $Diploid$ organisms,a harmful recessive mutation can be masked by a dominant wild-type allele on the homologous chromosome.

Most mutations have harmful effects on which of the following?
