Principles of Inheritance and Variation question

2004 · Q62

NEETBiologyPrinciples of Inheritance and VariationMCQ+4 / −1
One of the parents of a cross has a mutation in its mitochondria. In that cross, that parent is taken as a male. During segregation of F2 progenies that mutation is found in -
  1. A
    50% of the progenies
  2. B
    1/3 of the progenies
  3. C
    None of the progenies
  4. D
    All the progenies
View written solutionFree

Correct answer: C

Mitochondria is an organelle present in the cytoplasm. A zygote receives its cytoplasm from the female parent gamete. Hence in the given question, the F2 progenies receive the mitochondrial genome from the male parent, so mutation is not passed to progenies.
