When plants that are heterozygous for round seeds are crossed, what is the probability that the offspring will have wrinkled seeds? a 25 percentb 50 percentc 75 percentd 100 percent

The correct answer is A. 25 percent

Explanation:

Let R is the dominant allele that gives round seed and r is the recessive allele that code for wrinkled seeds. So as the parent plants are heterozygous for round seed that means they have genotype Rr.  

When they will cross with each other than 25% of the offspring would be wrinkled because only individuals with homozygous recessive genotype i.e, rr would be wrinkled and out of 4 only 1 individual with rr genotype would be produced.  

                           R    r

                  R      Rr   Rr

                  r       Rr   rr

Therefore the correct answer is A. 25 percent.

i think it's they require warm air

explanation:

tornados usually happen when it's raining right so when it's raining it cools down so if the temperature keeps changing then i think a tornado occurs sorry if it's wrong

the answer is c
