Red-flowered snapdragons are crossed with white-flowered snapdragons, producing all pink snapdragons in the f1 generation. what would you expect if you crossed pink with pink? , .
they are all 1/4, 1/2, or 3/4

I suggest you to choose the last option as they are all 3/4

1:1/2
2:1/4
3:1/4
hope this is right 
not 100% sure

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
