In pea plants the allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive. Under what conditions would we observe wrinkled seeds in a pea plant? When the plant has a genotype RR When the plant inherits a dominant allele from both parents When the plant inherits a recessive allele from both parents When a plant has a heterozygous allelic pair of the gene for seed shape

im positive its the third one, im doing the test right now and it common sense that if the parents BOTH have a recessive allele, the offspring would too.

In pea plants the allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive, Under the following conditions would we observe wrinkled seeds in a pea plant: When the plant inherits a recessive allele from both parents.

In pea plants the allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive.

  • The plant with round seeds would have genotype RR.
  • The plant with genotype rr would have wrinkled seeds.
  • As we know that the recessive allele is only expressed when there is no dominant allele present so,
  • RR is dominant as both alleles are dominant
  • Rr is a heterozygous condition where one dominant allele comes from one parent and one recessive allele comes from another parent.
  • rr is possible which is wrinkled seed shape, only if each parent plant contributes one recessive allele.

Cross can show the possible condition:

  R      r

R  RR    Rr

r   Rr      rr

In the given condition recessive allele is only possible when each parent gives one r or recessive allele.
