Mutant alleles that produce either no protein product or one that exists but is nonfunctional.
leaky mutations
mutant alleles that produce proteins showing some low residual function.
allelic series
complete set of known alleles of one gene
describes a gene that, in a diploid cell, can promote wild-type function in only one copy (dose)
describes a gene that, in a diploid cell, cannot promote wild-type function in only one copy (dose)
full, or complete, dominance
the homozygous dominant cannot be distinguished from the heterozygote
incomplete dominance
describes the general case in which the phenotype of a heterozygote is intermediate between those of the two homozygotes
the expression in a heterozygote of both the phenotypes normally shown by the two alleles
Clover is common name for which genus? What is the V pattern on their leaves called?
Trifolium, chevron
lethal alleles
mutant alleles that are capable of causing the death of an organism
temperature sensitive (ts) mutations
their phenotype is wild type at the PERMISSIVE TEMPERATURE (often room temperature), but mutant at the RESTRICTIVE TEMPERATURE.
PAH cofactor
harebell plant genus
double mutant
genotype with mutant alleles of two different genes
epistatic mutation
mutation at one locus which overrides another in a double mutant
a mutation at one locus which is overridden by a mutation at another
mutant allele at one gene that reverses the effect of a mutation of another gene, resulting in a wild-type or near wild-type phenotype (205)
wild type organisms that are merely reversals of the original mutational event (205)
