Select all examples of mutations that are likely to be recessive to wild-type alleles. check all that apply a null allele of gene x, if gene x is haploinsufficient. a null allele of gene x, if gene x is haploinsufficient. a hypermorphic allele of gene z that encodes a constitutively active protein. a hypermorphic allele of gene z that encodes a constitutively active protein. a hypomorphic allele of gene w that reduces its activity by 40%, when one wild-type allele of gene w is sufficient for wild-type phenotype. a hypomorphic allele of gene w that reduces its activity by 40%, when one wild-type allele of gene w is sufficient for wild-type phenotype. a null allele of gene y, if one wild-type allele of gene y is sufficient for a wild-type phenotype.
