Question

In a cross between a pea plant heterozygous for round seeds (Rr) and a plant with wrinkled seeds (rr), what is the expected phenotypic ratio of the offspring?

• A. 1 Round : 1 Wrinkled
• B. 3 Round : 1 Wrinkled
• C. All Round
• D. All Wrinkled

Hint:

In a monohybrid cross involving a heterozygous parent (Rr) and a homozygous recessive parent (rr), the phenotypic ratio is always 1:1, as half the offspring inherit the dominant allele and half inherit the recessive allele.
