Consider why no two people look exactly alike.
3Question 3.
What is the main focus of Mendel's research?
- Inheritance of traits
- Human genetics

4Question 4.
True or False: A mutation is always harmful.
- True
- False
Show hintHide hint
Consider examples of beneficial mutations.
Question 5.
A plant exhibits incomplete dominance for flower color, with red and white flowers producing pink offspring. If two pink flowers are crossed, what are the expected phenotypic ratios of their offspring?
Show hintHide hint
Use a Punnett square to determine the ratios.
Question 6.
In a cross between two pea plants, one homozygous dominant for a trait (TT) and one homozygous recessive (tt) produces a hybrid. What gametes can each parent produce, and what will be the genotype of the offspring?
Show hintHide hint
Remember how alleles segregate during gamete formation.
