Punnett Squares

S= DOMINANT

s= Recessive

each square is 25%

You don't have to solve them all but i'm trying to study from this, how would i go about solving it using a punnett square, one or two of the questions solved would be helpful, with an explanation.


  1. state the probability that a homozygous dominant pea plant passes down an S allele to its offspring? What about an s allele?
  2. state probability that, when crossing a true-breeding smooth pea plant with a true-breeding wrinkled pea plant, that we get a heterozygous offspring?
  3. If we did an experiment and cross two heterozygous pea plants, what is the probability of a heterozygous offspring?
  4. If we did an experiment and cross two heterozygous pea plants, what is the probability of a homozygous dominant OR a homozygous recessive offspring?
