Genome Screening

Biology: AQA GCSE Higher, topic 6.1.24

Embryonic Screening

Embryonic screening is a form of genome screening. We can screen a person's genome to look for genes that may make that person susceptible (vulnerable) to genetic disorders. The advantages of embryonic screening are:

Prevent suffering

Prevent suffering

  • It could prevent people from suffering from genetic disorders.
IVF embryos

IVF embryos

  • During IVF, most embryos are surplus to requirements anyway.
  • In this case, screening would merely ensure that the implanted embryos are healthy.
Financial saving

Financial saving

  • A reduction in disorders that need to be treated would save a significant amount of money in the long-term.

Test yourself on Genome Screening

  • What is not a genuine advantage of embryonic screening?

  • Why would embryonic screening save money in the long-term?

  • Why does only implanting embryos without disorder-causing genes help prevent suffering?

  • Why does screening surplus IVF embryos not reduce the number of embryos available for implantation?
