In Mendel's experiments, which trait is described as 'dominant'?
Answer: A trait that is expressed when at least one dominant allele is present
A dominant trait is expressed in the phenotype whenever at least one dominant allele is present.
What term describes an organism with two identical alleles for a trait (e.g., TT or tt)?
Answer: Homozygous
Homozygous means both alleles for a gene are the same, either both dominant (TT) or both recessive (tt).
Which type of cell division produces gametes (sperm and egg cells)?
Answer: Meiosis
Meiosis produces four haploid daughter cells (gametes) with half the chromosome number for sexual reproduction.
What is the role of ribosomes in a cell?
Answer: Synthesize proteins
Ribosomes translate mRNA into proteins, carrying out the final step of gene expression.
Which of the following is an example of a producer in an ecosystem?
Answer: Grass
Producers, such as grass, make their own food via photosynthesis and form the base of the food chain.
Natural selection acts on an organism's:
Answer: Phenotype
Natural selection acts on observable traits (phenotype), which then indirectly affects the frequency of underlying alleles.
