Dominant At Biology Glossary

What is it? The phenotype that is observed when two alleles of a gene are present in a cell. The gene whose phenotype is expressed is the dominant allele and the allele whose phenotype is masked is the recessive allele. If the phenotype of the diploid is inte rmediate between that of the two haploid genes, then the alleles are co-dominant.

Bio Term selective system is An experimental technique that enhances the recovery of specific (usually rare) genotypes.

Bio Term complementation test is A mating test to determine whether two different recessive mutations (a1;a2) on opposite chromosomes (trans, a1+/+a2) of a diploid or partial diploid will not complement (ie have a mutant phenotype) each other; but the same two recessive mutations on the same chromosome (cis, a1a2/++) in a diploid or partial diploid show a wild-type phenotype; a test for allelism. A test to determine whether two mutant sites are in the same functional unit or gene.

Bio Term allosteric transition is A change from one conformation of a protein to another.

Bio Term Restriction is The cleavage of double-stranded DNA by an endonuclease (restriction enzyme). The restriction enzyme distinguishes between self and foreign DNA based upon the modification of its DNA-binding site (for example, by methylation).

Bio Term non-recombinant is In mapping studies the offspring that have alleles arranged as in the original parents are non-recombinants.
