Question
________ If Professor Maciaszek breeding an award winning orchid and only hasa single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants? A) Backtrack through her previous experiments to obtain another plant with the same traits. B) Breed this plant with another plant with much weaker traits. C) Clone the plant asexually to produce an identical one. D) Force the plant to self-pollinate to obtain an identical one. E) Add nitrogen to the soil of the offspring of this plant so the desired traits continue. ________ The human genome is minimally contained in which of the following? A) every human cell B) each human chromosome C) the entire DNA of a single human D) the entire human population E) each human gene ______ A bacterial genome would be what? A. One pair of linear chromosomes B. One linear chromosomes C. One pair of circular chromosomes D. One circular chromosomes E. Random fragments of DNA ________ Why did the F_1 offspring of Mendel's classic pea cross always look like one of the two parental varieties? A) No genes interacted to produce the parental phenotype. B) Each allele affected phenotypic expression. C) The traits blended together during fertilization. D)One phenotype was completely dominant over another. E) Different genes interacted to produce the parental phenotype. ________How many unique gametes could be produced through independent assortment by an individual with the genotype AABbCcDdEEFfGg? A) 8 B) 16 C) 32 D) 64 E) 128 ________ Why did Mendel continue some of his experiments to the F_2 or F_3 generation? A) to obtain a larger number of offspring on which to base statistics B) to observe whether or not a recessive reappear trait would reappear C) to observe whether or not the dominant trait would reappear D) to distinguish which alleles were segregating E) to be able to describe the frequency of recombinationExplanation / Answer
