When an albino plant of maize (female) is crossed with normal green plant (male) all plants in the progeny are albino because___________________?
Correct answer: D. Plastids are inherited through maternal parents
- A. Albinism is dominant over green characters
- B. Green plastids of male parent become nitrated
- C. Crossing over results in structural changes in green plastids
- D. Plastids are inherited through maternal parents
Explanation
Maize plastids are transmitted mainly through the female parent, so the albino female determines the plastid phenotype of the progeny. This is cytoplasmic or maternal inheritance rather than Mendelian dominance or crossing over.
