Biology Question on Principles of Inheritance and Variation
Genes for cytoplasmic male sterility in plants are generally located in
A
mitochondrial genome
B
cytoso
C
chloroplast genome
D
nuclear genome
Answer
mitochondrial genome
Explanation
Solution
Cytoplasmic male sterility (CMS) in plants is typically associated with mutations or genes located in the mitochondrial genome. These mutations disrupt the normal development of male reproductive structures (such as pollen) and result in male sterility. This trait is often exploited in plant breeding to facilitate hybrid seed production.
So, the correct option is (A): mitochondrial genome
