Low Excellence

At Excellence the standard requires the student to demonstrate comprehensive understanding of human manipulations of genetic transfer (EN 3) and its biological implications (EN 2). This involves linking biological ideas about human manipulations of genetic transfer and its biological implications, which may involve the impact on (EN4):

  • ecosystems
  • genetic biodiversity
  • health or survival of individuals
  • survival of populations
  • evolution of populations.

The student provides evidence that just meets the criteria for Excellence by describing the human manipulation of cloning (1), explaining how the genetic manipulation occurs (2), and describing selective breeding (3).

The biological implications and their impact or consequences relating to each of these manipulations have also been presented:

  • Cloning on the health and survival of the individual (4), supported by a good biological explanation (5) and genetic biodiversity (6) including consequences, e.g. susceptibility to disease and supported with an example (7)
  • Selective breeding on genetic biodiversity and the related consequences, e.g. inbreeding depression (8) and the health and survival of the individual (9). The student has also linked two implications and their consequences (10) to consider the differences between selective breeding and natural selection (11).

The student has made comparisons between the benefits and cost effectiveness (economical implication) of using both manipulations (12) and linked them to decreased biodiversity and survival of populations (13).

The student could more convincingly secure this grade at Excellence by providing more supporting evidence using biological terms at Level 8 of the curriculum.
