Final Flashcards
Principle of dominance
Some alleles are dominant and others are recessive
In the p generation a tall plant was crossed with a short plant if alleles did not segregate
All of the f2 plants would be tall
In the p generation a tall plant is crossed with a short plant the probability that an f2 plant will be tall is
75%
