5 Multiple choice questions
- The occurrence in a population (or among populations) of several phenotypic forms associated with alleles of one gene or homologs of one chromosome.
- A mutation that confers a mutant phenotype but still retains a low but detectable level of wild-type function.
- Refers to a genotype such as A/A.
- An individual organism that is homozygous.
- An organism or cell carrying a mutation.
5 True/False questions
translation → The ribosome- and tRNA-mediated production of a polypeptide whose amino acid sequence is derived from the codon sequence of an mRNA molecule.
maternal inheritance → A type of uniparental inheritance in which all progeny have the genotype and phenotype of the parent acting as the female.
Northern blotting → The classical approach to genetic analysis, in which genes are first identified by mutant alleles and mutant phenotypes and later cloned and subjected to molecular analysis.
tetrad → More or less synonymous with phenotype.
monohybrid cross → A situation in which an F1 is larger or healthier than its two different pure parental lines.
