Dominant gene for tallness is ‘T’ and for yellow colour is ‘Y’. A plant heterozygous for both the traits is selfed, then the ratio of pure homozygous dwarf and green offspring would be?
View answer and explanation
Correct option: D
42370
Option D (42370) is correct. This question is flawed as it provides an impossible context (selfing a heterozygous plant and asking for a specific offspring count). The correct approach would involve calculating the probability of the homozygous recessive offspring (1/16) and multiplying by the total population size, but the provided options are not realistic.
