5 Matching questions

  1. chi-square (χ2) test
  2. mitochondrial DNA (mtDNA)
  3. heterogametic sex
  4. cytoplasmic segregation
  5. genotype
  1. a A statistical test used to determine the probability of obtaining observed proportions by chance, under a specific hypothesis.
  2. b The sex that has heteromorphic sex chromosomes (e.g., XY) and hence produces two different kinds of gametes with respect to the sex chromosomes.
  3. c The allelic composition of an individual or of a cell—either of the entire genome or, more commonly, of a certain gene or a set of genes.
  4. d The subset of the genome found in the mitochondrion, specializing in providing some of the organelle's functions
  5. e Segregation in which genetically different daughter cells arise from a progenitor that is a cytohet.

5 Multiple choice questions

  1. A double heterozygote such as A/a · B/b.
  2. A type of uniparental inheritance in which all progeny have the genotype and phenotype of the parent acting as the female.
  3. A section of RNA (three nucleotides in length) that encodes a single amino acid
  4. To fertilize eggs with sperms from the same individual.
  5. A cell in which meiosis takes place.

5 True/False questions

  1. genomeThe entire complement of genetic material in a chromosome set.


  2. heterozygous gene pairA gene present in only one copy in a diploid organism—for example, an X-linked gene in a male mammal.


  3. gene discoveryThe process whereby geneticists find a set of genes affecting some biological process of interest by the single-gene inheritance patterns of their mutant alleles or by genomic analysis.


  4. polymerase chain reaction (PCR)The two strains or individual organisms that constitute the start of a genetic breeding experiment; their progeny constitute the F1 generation.


  5. geneThe entire complement of genetic material in a chromosome set.
