A normal green male maize is crossed with albino female. The progeny is albino because:
Correct answer: C. Plastids are inherited from female parent
- A. Trait for a albinism is dominant
- B. The albinos have a biochemical to destroy plastids derived from green male
- C. Plastids are inherited from female parent
- D. Green plastids of male must have mutated
Explanation
The correct option is c) Plastids are inherited from the female parent. In plants, plastids, including chloroplasts, are typically inherited maternally. This means that the progeny receive plastids from the female parent. In the given cross, if the female parent is albino and does not have functional chloroplasts, the progeny will also lack chloroplasts and appear albino. Therefore, this option is correct.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
