D. The Vacuole is the correct answer!
<h3><u>Answer</u>;</h3>
Genes;
- are specific nucleotide sequences
- are located in a specific place on a chromosome
- determine the traits of an organism
<h3><u>Explanation;</u></h3>
- Genes are the basic physical and functional units of heredity. They consists of a specific sequence of nucleotides at a given position on a given chromosome that codes for a specific protein.
- Genes consist of three types of nucleotide sequence: coding regions, called exons, which specify a sequence of amino acids, non-coding regions, called introns, which do not specify amino acids and regulatory sequences, which play a role in determining when and where the protein is made.
I think you mean Round could be RR or Rr (round is dominant to wrinkled)
R=round
r=wrinkled
RR would be round phenotypically
Rr would be round phenotypically
To determine if they are RR or Rr you should perform a backcross with a wrinkled mutant!
I put a picture to demonstrate this.
If they are RR then if you cross with rr you would only get phenotypically Round pea plants.
If they are Rr then if you cross with rr you would get 50% round and 50% wrinkled. Any wrinkled? Definitely the heterozygote Rr!!
