Correct Statement: The interlocking bricks are the chromosomes.
- Explanation: The analogy uses the manual to represent the instructions for building, which correlates to how genes instruct for proteins, while the interlocking bricks represent chromosomes that contain multiple genes.
-
Correct Statement: They contain genetic material.
- Explanation: Both chromosomes and genes are integral components of the genetic information in an organism. Genes are segments of DNA, and chromosomes are structures made of DNA that contain many genes.
-
Correct Phenotype: Round.
- Explanation: Since the allele for round peas (R) is dominant over the allele for wrinkled peas (r), a pea plant with the genotype Rr (heterozygous) will express the dominant phenotype, which is round peas.
1.A manual contains instructions for how to build a variety of structures using a set of interlocking bricks. If this scenario is used as a model for genetic information which statement is correct?
Each set of instructions is a protein
The interlocking Brock's are the chromosomes
The manual is a chromosome
Each structure is a gene
2. How are chromosomes and genes alike?
They both encode a single protein
They are both part of DNA
They contain genetic material
They are both found on chromatids
3. In pea plants the allele for rounds, R, is dominant over the allele for wrinkled peas, r. What is the phenotype of a pea plant with genotype Rr?
Slightly wrinkled
Wrinkled
Round
Some round and some wrinkled
