Worked practice questions
A trait set by one locus with dominant or recessive alleles is a:
- Quantitative trait
- Polygenic trait
- Mendelian trait
- Pleiotropic trait
Show answer and solution
Correct answer: C. Mendelian trait
A Mendelian trait depends on a single locus whose alleles are dominant or recessive.
Mendel's uniformity rule applies to all individuals of which generation?
- F3 generation
- F1 generation
- F2 generation
- P generation
Show answer and solution
Correct answer: B. F1 generation
Crossing two pure-bred parents gives an F1 that is uniform in genotype and phenotype.
