According to the text, why is pedigree analysis used to study human genetics instead of breeding experiments?

  • A: Human traits are too complex to be studied by breeding.
  • B: Long generation span, few offspring, and ethical concerns.
  • C: It is impossible to determine the genotype of humans.
  • D: Mendelian patterns of inheritance do not apply to humans.

Explanation

The text explicitly states three reasons why humans are not convenient subjects for genetic research: 'The human generation span is long about 20 years , human parents produce many fewer offspring than peas, and breeding experiments would be unethical!'
