What are my alleles?
Different versions of a gene are called alleles.
Alleles are described as either dominant or recessive depending on their associated traits.
An example of this is the blood group AB which is the result of codominance of the A and B dominant alleles..
What does a complementation test tell you?
Complementation test, also called cis-trans test, in genetics, test for determining whether two mutations associated with a specific phenotype represent two different forms of the same gene (alleles) or are variations of two different genes. …
What are the 4 types of mutation?
There are three types of DNA Mutations: base substitutions, deletions and insertions.Base Substitutions. Single base substitutions are called point mutations, recall the point mutation Glu —–> Val which causes sickle-cell disease.Deletions. … Insertions.

What are conditional mutations?
A mutation that has the wild-type phenotype under certain (permissive) environmental conditions and a mutant phenotype under other (restrictive) conditions.
How do you tell if mutations are on the same gene?
A complementation test (sometimes called a “cis-trans” test) can be used to test whether the mutations in two strains are in different genes….Complementation (genetics)Mutations occur in the same gene.One mutation affects the expression of the other.One mutation may result in an inhibitory product.
How do you determine if a mutation is dominant or recessive?
Figure 8-1 For a recessive mutation to give rise to a mutant phenotype in a diploid organism, both alleles must carry the mutation. However, one copy of a dominant mutant allele leads to a mutant phenotype. Recessive mutations result in a loss of function, whereas dominant (more…)
Could you carry out a complementation test on two dominant mutations Why or why not?
Both mutations must be recessive. The complementation test will not work if either mutation exhibits dominance over the wild-type allele. … Mutations in the same gene can cause different homozygous phenotypes. If a gene functions in many processes, then mutations in this gene may impair each function independently.
