5 True/False questions
trait → The deliberate mating of two parental types of organisms in genetic analysis.
genotype → 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.
transfer RNA → A 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.
polymorphism → One form of a genetic polymorphism; the morph can be either a phenotype or a molecular sequence.
morph → 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.
