In pea plants round is dominant to wrinkled. A farmer has a field of round peas. He collects the peas and plants then for the following season. At the end of the following season he harvests 2000 pounds of peas and notices that some of them are wrinkled. List the genotypes of the offspring pea plants. What were the possible genotypes of the parental pea plants?

RR Rr and rr. RR and Rr will look Round. The rr will be wrinkled.

The parent plants were most likely Rr genotypes.

Explanation:

Some offspring received two of the R genes. Some received one R and one r, so they will be round too. The offspring with two r genes will be wrinkled, and their offspring will be wrinkled too unless they cross with an RR or Rr parent.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.
