Question 33

A pea plant carries one dominant allele and one recessive allele for flower colour. What happens to the recessive allele?

  1. It is destroyed by the dominant allele
  2. It slowly changes into a copy of the dominant allele
  3. It stays and can be passed to offspringCorrect answer
  4. It leaves the cell as the plant grows

Explanation

Masking changes only what is seen; the DNA of the hidden allele is untouched, and about half the gametes the plant makes will carry it. If the allele were destroyed or rewritten, a hidden characteristic could never reappear in a later generation, yet it regularly does.
