Answer 1

The probability that the offspring will have wrinkled seeds is 25 percent or 1/4 in a monohybrid cross.

Step-by-step explanation:

The probability that the offspring will have wrinkled seeds can be determined using a Punnett square. Since both plants are heterozygous for seed shape (Rr), the genotypes of the parent plants are Rr (round seeds) and Rr (round seeds). When these genotypes are crossed, the possible genotypes of the offspring are RR (round seeds), Rr (round seeds), and rr (wrinkled seeds).

Thus, the probability of the offspring having wrinkled seeds (rr genotype) is 25 percent or 1/4 in a monohybrid cross.
