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?\n25 percent\n50 percent\n75 percent\n100 percent

Answer

Explanation:

Step1: Define alleles

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

Step2: Set up the 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 possible combinations are: RR, Rr, Rr, and rr.

Step3: Calculate the probability

The genotype for wrinkled seeds is rr. Out of the 4 possible genotypes in the Punnett - square, 1 is rr. So the probability is $\frac{1}{4}$ or 25%.

Answer:

25 percent
