two plants are heterozygous for seed shape and have round seeds. if the two plants are crossed, what is the probability that the offspring will have wrinkled seeds?\no 25 percent\no 50 percent\no 75 percent\no 100 percent

Answer

Explanation:

Step1: Define alleles

Let R represent the dominant allele for round seeds and r represent the recessive allele for wrinkled seeds. Heterozygous plants have the genotype Rr.

Step2: Set up Punnett - square

When two Rr plants are crossed, the possible gametes from each parent are R and r. The Punnett - square has 4 boxes. The combinations are RR, Rr, Rr, and rr.

Step3: Calculate probability

Out of the 4 possible genotypes in the offspring (RR:Rr:Rr:rr), only 1 has the genotype rr (wrinkled seeds). So the probability is $\frac{1}{4}$ or 25%.

Answer:

25 percent
