Practice questions testing deep understanding of Mendel's laws, Punnett squares, and inheritance.
Q1. A man with brown eyes (heterozygous, Bb) marries a woman with blue eyes (homozygous recessive, bb). If they have four children, what is the mathematical probability that any one child will have blue eyes? Draw a mental Punnett square to justify your answer.
Q2. Why did Gregor Mendel choose pea plants (Pisum sativum) for his genetics experiments instead of a mammal like a mouse? State two biological reasons.
Q3. Assertion (A): The sex of a human child is determined entirely by the father. Reason (R): Human females only produce eggs containing the X chromosome, whereas human males produce sperm carrying either the X or the Y chromosome. If a Y-carrying sperm fertilizes the egg, the child is male.
