5 Matching questions

  1. meiosis
  2. recombinant
  3. haploid number
  4. dioecious species
  5. haploinsufficient (Sec. 2.3.3)
  1. a Two successive nuclear divisions (with corresponding cell divisions) that produce gametes (in animals) or sexual spores (in plants and fungi) that have one-half of the genetic material of the original cell.
  2. b ...
  3. c A plant species in which male and female organs are on separate plants.
  4. d Refers to an individual organism or cell having a genotype produced by recombination.
  5. e The number of chromosomes in the basic genomic set of a species.

5 Multiple choice questions

  1. (1) The study of genes. (2) The study of inheritance.
  2. Small regions at the ends of the X and Y sex chromosomes; they are homologous and undergo pairing and crossing over at meiosis.
  3. One of a pair of sex chromosomes, distinguished from the X chromosome.
  4. One of the different forms of a gene that can exist at a single locus.
  5. A chain of linked amino acids; a protein.

5 True/False questions

  1. traitThe deliberate mating of two parental types of organisms in genetic analysis.

          

  2. genotypeThe 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.

          

  3. transfer RNAA class of small RNA molecules that bear specific amino acids to the ribosome in the course of translation; an amino acid is inserted into the growing polypeptide chain when the anticodon of the corresponding tRNA pairs with a codon on the mRNA being translated.

          

  4. polymorphismOne form of a genetic polymorphism; the morph can be either a phenotype or a molecular sequence.

          

  5. morphTwo successive nuclear divisions (with corresponding cell divisions) that produce gametes (in animals) or sexual spores (in plants and fungi) that have one-half of the genetic material of the original cell.
