Genetics exam test questions and answers
graded A+
1. alleles ditterent forms of a gene (G and g)
2. allelic an individual that has two variants of a gene (Gg)
3. non allelic an individual has two copies of the same form of a
gene (GG or gg)
4. for two genes to be map on the same locus on homologous
considered alleles they chromsomes
must..
5. wild type the phenotype of the typical form of a species as it
occurs in nature
6. null allele A mutant allele that produces no functional gene
product. Usually inherited as a recessive trait.
7. incomplete dominance Situation in which one allele is not completely
dominant over
another allele
8. penetrance the frequency with which individuals of a given
genotype manifest at least some degree of the
trait.

mutant
phenotype
