- a The situation in which the phenotypes of both alleles are exhibited in the heterozygote because both alleles affect the phenotype in separate, distinguishable ways.
- b The situation in which the phenotypes of the heterozygote and dominant homozygote are indistinguishable.
- c A heritable feature that varies continuously over a range rather than in either-or fashion.
- d The range of phenotypes produced by a single genotype due to environmental influences.
- e An additive effect of two or more genes on a single phenotypic character.
5 Multiple Choice Questions
- The genetic makeup or set of alleles of an organism.
- An observable, heritable feature
- The parent individuals from which offspring are derived in studies of inheritance.
- A human genetic disease caused by a recessive allele for a dysfunctional enzyme, leading to accumulation of certain lipids in the brain. Seizures, blindness, and degeneration of motor and mental performance usually become manifest a few months after birth followed by death within a few years.
- Having two identical alleles for the same gene.
