Group of answer choices
Incomplete dominance
Complementation
Maternal effect
Recessive lethality
2)Wild-type plants of the squash family synthesize a bitterchemical, cucurbitacin, that is toxic.
Through selective breeding, gardeners created squash varietiesthat are edible; these carry mutations in the enzymes needed tosynthesize cucurbitacin. However, cross-pollination betweendifferent varieties with mutations in different genes producesprogeny that are toxic!
This is an example of:
Group of answer choices
1-Maternal effect
2-Complementation
3-Recessive lethality
4-Incomplete penetrance
