السؤال 33

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

It is destroyed by the dominant allele
It slowly changes into a copy of the dominant allele
It stays and can be passed to offspringالإجابة الصحيحة
It leaves the cell as the plant grows

الشرح

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.
